Data Center Migration — How to Choose the Right Colocation Facility
Data center migration is one of the most consequential infrastructure decisions a mid-market company makes. The facility you choose, the contract terms you sign, and the architecture decisions you make during the migration define your infrastructure costs and capabilities for the next three to five years.
Whether you are planning a full data center relocation, a server relocation from an on-premise environment, or a colocation migration from one provider to another — the decisions made during the evaluation process define your infrastructure economics for years. Companies evaluating data center migration companies or independent advisors for the first time consistently find that independent advisory produces better contract terms at no additional cost.
The New York data center market is one of the most supply-constrained in the world — making independent advisory more valuable here than in almost any other US market.
Most companies navigate this process without independent guidance — evaluating facilities directly, negotiating without benchmark data, and signing contracts they will spend years regretting. This guide covers everything mid-market companies need to know before, during, and after a data center migration — and how an independent advisor changes the outcome.
Consider this your independent data center migration review — written by an advisor with no financial stake in which facility or provider you choose.
Data center migration outcomes are defined almost entirely by the evaluation process — not the move itself. Companies that run a simultaneous competitive evaluation across multiple providers before signing anything consistently achieve 15 to 30 percent better pricing and meaningfully better contract terms than companies that evaluate providers sequentially. Metro Colo Advisory runs that process for you at no cost — facility shortlisting, RFP management, current benchmark pricing, and contract review across every major NYC provider.
Data Center Migration Scenarios — Which Path Fits Your Situation
The following table summarizes the four most common data center migration scenarios and the primary evaluation criteria for each. Use this as a starting point for understanding which migration path applies to your situation before engaging providers.
| Migration Scenario | Primary Driver | Typical Timeline | Hardware Purchase Required | Recommended NYC Facility Types |
|---|---|---|---|---|
| On-premise to colocation | Reliability, compliance, operational burden | 8-16 weeks | Sometimes (refresh existing) | Equinix NY4/NY5, CoreSite NY2/NY3, DataBank 165 Halsey |
| Provider to provider (contract expiration) | Pricing, performance, contract terms | 6-12 weeks | No (existing hardware moves) | All providers — competitive RFP critical |
| Cloud repatriation (AWS/Azure to colo) | Cost reduction, predictability, compliance | 10-20 weeks | Yes (new hardware purchase) | DataBank LGA3 (AI workloads), CoreSite (hybrid cloud) |
| Legacy facility to modern infrastructure | Power density, cooling, GPU support | 8-16 weeks | Sometimes (GPU refresh) | DataBank LGA3, CoreSite NY3 |
Each scenario has distinct evaluation criteria, timeline considerations, and resource requirements. Metro Colo Advisory tailors the migration evaluation process to your specific scenario at no cost.
What Is Data Center Migration, And Why
Companies Undertake It
Data center migration is the process of moving IT infrastructure — servers, storage, networking equipment, applications — from one location to another. The destination varies:
Moving from an on-premise server room or corporate data center to a professional colocation facility. Moving from one colocation provider to another — driven by contract expiration, pricing, performance, or changing requirements. Moving from public cloud back to dedicated colocation infrastructure — sometimes called cloud repatriation. Moving from a legacy facility to a purpose-built modern facility with better power density, cooling, or connectivity.
Each scenario has different drivers, different timelines, and different evaluation criteria. What they share is the need for independent guidance before committing to a new facility and a long-term contract.
The Most Common Data Center Migration Scenarios
On-Premise to Colocation
Companies outgrowing their own server rooms — or simply tired of the operational burden of running them — move to professional colocation facilities. The drivers are usually a combination of reliability, compliance requirements, connectivity, and the desire to stop managing physical infrastructure. For mid-market companies this is typically the first time they have evaluated the colocation market and the learning curve is steep without an advisor.
Provider to Provider Migration
Contract renewal is the most common trigger. A company in colocation for three to five years whose contract is expiring has the opportunity to renegotiate — or to evaluate the full market and potentially move to a better-fit facility at better pricing. Without current market benchmark data most companies renew at whatever rate their current provider offers. That is almost always above market. Companies evaluating data center rental arrangements or flexible data center for lease terms find that contract flexibility varies significantly between providers — an area where independent advisory produces meaningful improvements. Cologix Parsippany is also worth evaluating for cost-sensitive migrations and disaster recovery deployments where geographic separation from Manhattan is required. See our NYC colocation provider comparison for full context.
Cloud to Colocation — Repatriation
Companies spending above $30,000 monthly on AWS or Azure for stable predictable workloads increasingly find the economics favor dedicated colocation infrastructure. Moving stable workloads from cloud to owned hardware in a colocation facility typically reduces infrastructure costs by 40 to 60 percent for the right workload profile. For a detailed analysis of this specific migration scenario see our cloud repatriation guide.
Legacy Facility to Modern Infrastructure
Older colocation facilities were built for 3 to 5 kilowatts per rack — standard enterprise compute from a different era. Companies running modern workloads — particularly AI, GPU, and high-density compute — increasingly find legacy facilities cannot support their power and cooling requirements. Migrating to purpose-built modern infrastructure unlocks capabilities the legacy facility simply cannot provide.
The Data Center Migration Process — Step by Step
Phase 1 — Requirements Definition (Weeks 1 to 2)
Before evaluating any facility you need a clear picture of your actual requirements. Power draw in kilowatts — not nameplate ratings, actual measured draw with growth headroom. Connectivity requirements — which carriers, cloud on-ramps, and network peers you need access to. Compliance requirements — SOC 2, HIPAA, PCI-DSS, and any industry-specific certifications. Physical space — cabinet count, cage versus suite depending on deployment size. Timeline — when your current lease expires or when your cloud costs become untenable.
Getting this wrong at Phase 1 creates problems at every subsequent phase. Underestimating power requirements leads to capacity constraints after you move in. Overlooking connectivity requirements means expensive retrofits after the contract is signed.
Phase 2 — Facility Evaluation and Shortlisting (Weeks 2 to 4)
With requirements defined you evaluate facilities against them.
Colocation site selection — choosing the right zone, provider, and facility for your specific requirements — is where most mid-market companies make their most expensive mistakes — evaluating only the facilities they already know, accepting list pricing without competitive context, and failing to understand which terms are negotiable.
An independent colocation advisor changes this phase entirely. Metro Colo Advisory runs your requirements against every major facility in your target market simultaneously, identifies the two to three that genuinely fit, and returns a shortlist with honest trade-off analysis within 72 hours. You get competitive quotes from multiple providers before talking to any of them — which creates the negotiating leverage that produces meaningful pricing improvement.
Phase 3 — Contract Negotiation (Weeks 3 to 6)
The facility contract is where the real money is won or lost. Monthly rate is only part of the story. Escalation clauses, auto-renewal provisions, minimum power commitments, remote hands caps, and early termination terms in any colocation contract have a significant financial impact over a three to five year term.
Most mid-market companies negotiate colocation contracts once every three to five years. Provider sales teams negotiate them every day. That experience gap is significant — and it is exactly what an independent advisor closes.
Phase 4 — Migration Planning (Weeks 4 to 10)
Once the contract is signed migration planning begins. Sequence matters — non-critical systems move first, production systems migrate after stability is confirmed. Connectivity is established before hardware arrives. Network relocation — including BGP announcements, carrier transitions, and IP address management — should begin in parallel with physical installation planning. It is frequently the most technically complex and time-sensitive component of the migration. Your team coordinates with the facility’s technical staff on physical installation. Timeline depends on deployment size and complexity — small deployments can complete in weeks, large complex migrations take months.
Phase 5 — Cutover and Stabilization (Weeks 8 to 16)
Production systems cut over to the new facility. DNS, routing, and application configurations update to reflect the new infrastructure. A parallel running period — where both old and new infrastructure stay live — provides a fallback if issues arise. Most companies are fully stabilized within 60 days of cutover.

How to Evaluate a Colocation Facility for Your Migration
Not all facilities are equal. These are the evaluation criteria that matter for mid-market data center migrations.
Power Capacity and Density
Your actual kilowatt requirement — not nameplate ratings — determines which facilities can accommodate you. Standard enterprise colocation supports 3 to 10 kilowatts per rack.
High-density deployments require 10 to 100 kilowatts per rack and above — purpose-built high density colocation infrastructure is required for these workloads. DataBank LGA3 supports deployments from single cabinet and 1U colocation configurations through to full cage and suite deployments — with purpose-built high density infrastructure that most legacy facilities cannot match.
Facilities that can’t support your density may tell you they can until your equipment arrives. Understanding exactly what a facility can deliver in your specific space is essential before signing.
Connectivity and Carrier Access
Carrier neutral data center facilities give you the most leverage on bandwidth pricing because carriers compete for your business directly Carrier-dense facilities — particularly Manhattan data centers and carrier hotels like 60 Hudson Street and 111 8th Avenue — offer unmatched connectivity options but at premium pricing. For companies where bandwidth cost and network diversity are primary drivers the carrier ecosystem at your chosen facility matters as much as the power and space.
Compliance Certifications
SOC 2 Type II, HIPAA Business Associate Agreement, PCI-DSS, and other certifications represent significant investment by the facility. Choosing a certified facility means inheriting that compliance infrastructure rather than building it from scratch. For mid-market companies in regulated industries — financial services, healthcare, legal — HIPAA colocation and compliance certification posture is often the primary selection criterion.
For a complete framework on how colocation compliance affects your specific industry — healthcare HIPAA, financial services SOC, PCI DSS, and SOC 2 — see our compliance colocation guide.
Geographic Location and Latency
For most mid-market applications geographic location within a metro market matters less than connectivity. But for latency-sensitive applications — financial trading, real-time AI inference, video production workflows — proximity to specific network infrastructure, exchanges, or cloud regions can be a primary factor. Understanding your actual latency requirements before selecting a facility prevents expensive realizations after the move.
Contract Flexibility and Provider Stability
A colocation facility is a long-term relationship. Provider financial stability, customer service reputation, and responsiveness during a competitive evaluation all signal what the relationship will look like once you are locked into a contract. An advisor who has worked with a provider across multiple client engagements has a much clearer picture of the post-contract experience than any due diligence process can reveal.
The Hidden Costs of Data Center Migration — What Most Companies Miss
Understanding data center colocation pricing in full — not just the monthly power and space rate — is the most important financial exercise before signing any colocation contract. Here are the costs most companies miss entirely:
Cross-Connect Fees
Every physical connection to a carrier, cloud provider, or other network requires a cross-connect — a physical cable with a monthly recurring fee. Mid-market deployments typically require 4 to 10 cross-connects. These are negotiable and frequently over-priced in initial proposals.
Setup and Installation Fees
One-time costs for space preparation, power installation, and initial connectivity configuration. Negotiable in competitive situations and often waived or reduced when multiple providers are competing for your business.
Hardware Procurement and Configuration
For on-premise to colocation migrations — or cloud repatriation — hardware procurement is a significant cost outside the facility contract itself. Server lead times for high-density GPU configurations currently run 12 to 20 weeks in some cases. Starting the hardware procurement process early is critical for migrations with hard deadlines.
Parallel Running Costs
During migration you typically pay for both your old and new infrastructure simultaneously — sometimes for 30 to 90 days. This parallel running period is unavoidable but planning for it prevents budget surprises.
Migration Labor
Physical server moves, network reconfiguration, application migration, and testing all require engineering time. For complex migrations the labor cost can exceed the first year of colocation fees. Understanding the full all-in cost of migration — not just the facility contract — produces a realistic ROI model. See our colocation pricing guide for a complete breakdown of what goes into a colocation contract.
Data Center Migration vs Server Relocation vs Cloud Repatriation — Understanding the Differences
These terms are often used interchangeably but represent distinct scenarios with different evaluation criteria.
- Data center migration is the broad category — any planned movement of IT infrastructure from one location to another. It includes server relocation, facility migrations, and cloud repatriation.
- Server relocation typically refers to moving individual servers or small deployments rather than entire data center operations. Lower complexity, shorter timeline, fewer evaluation criteria.
- Data center relocation is the physical movement of an entire data center operation — servers, networking, storage, and all associated infrastructure — from one facility to another. Higher complexity and risk than server relocation.
- Cloud repatriation is specifically the migration of workloads from public cloud infrastructure back to dedicated colocation. Driven by cost, compliance, or performance considerations. Requires hardware procurement in addition to facility selection.
- Network relocation covers the connectivity and networking components of a broader migration — BGP announcements, carrier transitions, IP address management. Often the most technically complex component of a data center migration.
Understanding which category your migration falls into determines the evaluation criteria, timeline, and resource requirements. See our independent provider comparison to understand which NYC facilities serve each migration scenario best.
Why Independent Advisory Changes Data Center Migration Outcomes
The colocation market is designed to work against buyers who negotiate directly. Provider sales teams have complete visibility into market pricing. Buyers entering the market every three to five years have almost none.
Metro Colo Advisory was built specifically to close that gap — giving mid-market companies the same market intelligence and negotiating leverage that providers have had to themselves for decades.
Metro Colo Advisory is an independent colocation broker — think of us the way you’d think of a buyer’s agent in real estate. We sit on your side of the table, negotiate with providers on your behalf, and get paid by the provider only when a deal closes. There is no cost to you.
Whether you need a colocation consultant for a one-time migration evaluation or an ongoing advisory relationship through a complex multi-phase migration — Metro Colo Advisory provides independent guidance at no cost to you.
For data center migrations specifically we provide:
- Current market benchmark pricing across every major facility in your target market — so you know whether the quote you received is competitive before you respond to it.
- Facility shortlisting based on your actual requirements — not just the facilities you already know about. We surface options that fit your power, connectivity, compliance, and budget requirements that you may never have evaluated independently.
- Contract review alongside legal review — identifying unfavorable terms, negotiating caps on escalation clauses, and making sure auto-renewal provisions don’t lock you into another term at whatever rate the provider decides to charge.
- Ongoing advisory relationship throughout migration — available as a resource for facility and provider questions that arise during the migration process.
- The commission we earn from the provider you choose is a standard part of their channel partner program. It does not affect your pricing. Going direct does not save you money — it just means you negotiated without an advisor.
Data Center Migration in the NYC Metro Market
For companies in the New York City metro area the data center NYC migration landscape has specific characteristics worth understanding before you start evaluating facilities.
The NYC metro colocation market is one of the most supply-constrained markets in the world. Vacancy rates at primary facilities have fallen to historic lows. Companies migrating to NYC facilities in 2026 are negotiating in a tighter market than existed two to three years ago — which makes having current market intelligence and competitive quotes more important than ever.
The three zones of the NYC metro market serve different migration scenarios:
Manhattan carrier hotels
60 Hudson Street, 111 8th Avenue, 32 Avenue of the Americas — serve companies where carrier density, financial ecosystem proximity, and Manhattan address matter. Premium pricing reflects the premium location and connectivity. Digital Realty operates the dominant Manhattan carrier hotel footprint at these addresses.
Secaucus
The Equinix data center campus including NY4 and NY5, CoreSite NY2 and NY3 — serves companies that need financial ecosystem proximity and serious connectivity at pricing that is meaningfully more competitive than Manhattan. The dominant choice for financial services companies migrating from on-premise infrastructure.
Orangeburg
DataBank LGA3 and LGA4 — serves companies migrating to high-density AI and GPU infrastructure, disaster recovery colocation deployments, and cost-sensitive primary deployments where Manhattan proximity is not required. One-hop connectivity to Manhattan locations maintains ecosystem access.
DataBank also operates a facility at 165 Halsey Street in Newark NJ — a carrier-neutral colocation option for companies needing New Jersey presence with direct connectivity to the Manhattan ecosystem at competitive pricing.
Metro Colo Advisory works with every major facility across all three zones of the NYC metro colocation market. Our migration advisory covers the full market with honest trade-off analysis for your specific requirements.
Frequently Asked Questions — Data Center Migration
How long does a data center migration actually take from start to finish?
A properly run data center migration takes 8 to 16 weeks from initial requirements definition through full cutover and stabilization for standard mid-market deployments. Phase 1 requirements definition takes one to two weeks. Phase 2 facility evaluation takes two to four weeks. Phase 3 contract negotiation takes one to three weeks. Phase 4 migration planning runs two to six weeks. Phase 5 cutover and stabilization runs four to eight weeks. Complex multi-site or cloud repatriation migrations can take 16 to 24 weeks. Compressed timelines are possible but produce worse outcomes — providers respond to urgency by reducing negotiating flexibility. Metro Colo Advisory manages the full migration timeline on your behalf at no cost.
What is the total cost of a data center migration including all hidden expenses?
Total data center migration cost includes the colocation facility contract plus hardware procurement, cross-connect fees, setup and installation fees, parallel running costs during cutover (typically 30 to 90 days of double-paying), migration labor, network reconfiguration, and contingency budget for unforeseen issues. For mid-market deployments hardware procurement and migration labor can exceed the first year of colocation fees combined. Cross-connect installation fees are frequently waived in competitive evaluations and represent meaningful negotiating leverage. Understanding the full all-in cost rather than just the facility monthly rate produces a realistic ROI model. Metro Colo Advisory models the complete migration cost including all hidden expenses for your specific scenario at no cost.
How do I know if the colocation pricing I was quoted is actually competitive?
Without current market benchmark data across multiple providers for comparable deployments you don’t. The gap between list pricing and what well-advised mid-market companies actually pay is consistently 15 to 30 percent on power rates and meaningfully more on cross-connect fees and setup costs. Provider sales teams have complete visibility into market pricing across all their competitors. Companies entering the market once every three to five years have almost none. An independent advisor with current deployments across every major NYC provider provides the benchmark data needed to evaluate any quote accurately. Metro Colo Advisory delivers current market benchmark pricing for your specific deployment requirements at no cost.
Does using an independent colocation broker actually help with data center migration?
Yes — for the same reason you would use a buyer’s agent when purchasing real estate. The broker is paid by the provider you choose, not by you. The commission exists whether you use an advisor or not. Going direct means negotiating without benchmark data against sales teams that negotiate every day. An independent advisor runs the simultaneous RFP process on your behalf, brings current benchmark pricing to every negotiation, identifies unfavorable contract terms before you sign, and provides ongoing support throughout the migration — at no cost to you. Companies using independent advisory consistently achieve 15 to 30 percent better pricing and meaningfully better contract terms than companies negotiating directly. Metro Colo Advisory provides this independent advisory at no cost.
Should I choose colocation or managed hosting when migrating my data center?
Standard colocation provides space, power, cooling, and connectivity — you manage your own equipment. Managed colocation adds facility staff managing your equipment on your behalf — monitoring, patching, reboots, and basic administration. Managed colocation costs more than standard colocation but less than fully managed hosting. For mid-market companies with internal IT capability standard colocation typically provides better economics and more operational control. For companies without internal infrastructure management capability managed colocation may be the right starting point. The right answer depends on your team’s capabilities and how much operational control you want to maintain. Metro Colo Advisory evaluates which model best fits your specific situation at no cost.
How do I make sure a colocation facility meets my HIPAA or SOC 2 compliance requirements?
Request current certification documentation — not website badges or legacy PDFs. For SOC 2 Type II request the full audit report and verify the report period is current and the scope covers the specific services and spaces you will use. For HIPAA request the facility’s Business Associate Agreement and have legal review the scope and terms before signing. For PCI DSS request the current Attestation of Compliance. For ISO 27001 request the current certificate with validity dates. Your facility’s certifications become part of your own compliance posture — a gap in facility certifications is a gap in your compliance program. Metro Colo Advisory verifies compliance documentation for your specific requirements before any provider commitment at no cost.
What is the difference between data center migration, data center relocation, and server relocation?
Data center migration is the broad category covering any planned movement of IT infrastructure from one location to another — it includes all sub-scenarios. Server relocation specifically refers to moving individual servers or small deployments rather than entire data center operations — lower complexity, shorter timeline, fewer evaluation criteria. Data center relocation is the physical movement of an entire data center operation from one facility to another — higher complexity and risk than server relocation. Cloud repatriation is specifically the migration of workloads from public cloud infrastructure back to dedicated colocation — requires hardware procurement in addition to facility selection. Network relocation covers connectivity and networking components of a broader migration — often the most technically complex component. Metro Colo Advisory tailors the evaluation process to your specific migration type at no cost.
When does data center migration to colocation make more financial sense than staying on-premise or in the cloud?
Data center migration to colocation typically makes financial sense in three scenarios. First, companies running stable predictable workloads on AWS or Azure above $30,000 monthly often find colocation reduces infrastructure costs by 40 to 60 percent over a two to three year period. Second, companies operating on-premise data centers approaching capacity, cooling, or compliance limits typically find professional colocation delivers better economics than continued on-premise investment. Third, companies with regulated industry compliance requirements that exceed on-premise capabilities often find facility certifications make the migration financially justified through compliance cost reduction alone. Use our cloud vs colo calculator to model your specific scenario. Metro Colo Advisory provides full TCO analysis comparing your current infrastructure to colocation alternatives at no cost.
What should I look for in a colocation facility for AI and GPU infrastructure migration?
AI and GPU infrastructure migration has specific requirements that standard enterprise colocation cannot meet. Power density above 10kW per rack — required for GPU infrastructure — needs purpose-built high density colocation infrastructure. Air cooling supports up to 35kW per rack with proper containment. Liquid cooling supports up to 100kW per rack and is required for B200 and GB200 GPU configurations. NVIDIA DGX Ready certification is the most reliable independent verification of a facility’s ability to support modern GPU infrastructure. DataBank LGA3 in Orangeburg is the primary independent recommendation for AI and GPU infrastructure migration in the NYC metro market — purpose-built high density colocation infrastructure at pricing consistently more competitive than alternatives. Metro Colo Advisory evaluates high density colocation options for your specific GPU deployment at no cost.
