Choose the destination by facts you can check, not by fashion. This guide is for IT heads, infrastructure managers and operations leads at mid-size companies in India and the GCC. They have decided on a data center migration, so the question is where to go. It compares the four data center migration options at the level of the whole estate: refresh in place, colocation, hybrid and cloud. It also says what each kind of provider does. The options are not exclusive, so you can mix them by workload.

Data Center Migration Options: The Short Answer
There are four estate-level destinations for a data center migration: refresh or consolidate in place, move to colocation, run a hybrid, or move to cloud. Six questions you can answer from records or a short conversation point to one of them. You then test that answer against each workload in your strategy. A mix is allowed. If you are not yet sure the estate needs to move, our signs of data center modernization guide helps you check.
The destination is one choice, while the method for each application is another, and the provider is a third. This guide covers the first and the last.
What We Mean by Options
Refresh or consolidate in place means you keep the facility, renew the hardware and, if you have several sites, reduce them to fewer. Consolidation is a variant of refresh. Colocation means renting space, power and cooling in another operator’s facility and keeping your own hardware there. A cross-connect is a direct cable link between two parties in the same facility.
Hybrid means running part of the estate in one place and part in another, with reliable links between them. Cloud means running workloads on a provider’s platform, which is what data center migration to cloud means for some or all of an estate. Our guide to the 7 Rs of cloud migration lists the application-level methods.
A workload is an application or service with its data and the systems it runs on. TechTarget (Julia Borgini, 14 July 2025) describes three main types of data center migration: consolidation, cloud, and colocation, meaning a move to another data center, usually a shared one. However, this guide treats consolidation as a variant of refresh in place.
Data Center Migration Options: Side by Side
The options differ most in who runs the facility, how quickly capacity changes and how much control you keep.
| Refresh in place | Colocation | Hybrid | Cloud | |
|---|---|---|---|---|
| Who runs the facility | You | The colocation operator | You and a provider | The cloud provider |
| How capacity changes | Planned purchases | Added space and power when agreed with the operator | Each side changes its own way | Adjusted on demand |
| Control of hardware and data location | Full | Your hardware, their building | Split between the two | Chosen from the provider’s options |
| Skills you need | Facility and hardware | Hardware and network | Both, plus linking them | Platform skills |
| What the first move leaves open | The facility’s own limits | Your hardware still ages | How the two sides connect | Dependencies left behind |
Key Takeaway So a table of facts beats a preference. Fill in the row for your own estate before you argue about the answer.
Data Center Migration Options: Six Questions That Choose
Answer six questions from records or a short conversation. Each answer points to an option, and you then test it against each workload.
If power, cooling and space are adequate, refresh in place stays on the table. If not, a different place is the answer.
Steady loads suit planned capacity, while variable demand suits capacity that changes on demand.
Specialized hardware, unusual security needs or fixed data location point toward your own hardware, in your building or in colocation.
Latency-sensitive systems and the data they use should sit together, so check that before you split them across sites.
Running a platform and running a facility need different people. So match the option to the team you have or can hire.
A lease end or end of vendor support can decide the first move.
These are our own questions, written from the job each option does. Also, where recovery needs shape the choice, our post on high availability vs disaster recovery explains what to ask.

Data Center Migration Options: When a Mix is Right
When no single option fits, split by workload. Typical splits are practice, not a rule: core databases and specialized hardware stay on site or sit in colocation, and a data center migration to cloud takes the variable and customer-facing services.
However, a mix adds effort. You have to connect the environments, secure them and govern them, so the links between sites become part of the design. Microsoft’s Cloud Adoption Framework advises connecting environments with reliable integration methods, and keeping split-environment time short. Our data center migration strategy guide covers the split-site period and the parts that cannot move yet.
Also, residency can shape a mix. Microsoft’s guidance says that where cross-region failover is allowed, you choose a secondary region inside the same residency boundary. Where it is not, you rely on in-region redundancy and backup and restore (Microsoft Learn, as of November 2026). This guide states no country rule.
Write down which workloads sit in which place and why, so the mix is a decision with reasons and not an accident of timing.
A mix with weak links between sites is slower and riskier than either end. Plan the links before you plan the split.
Data Center Migration Options: Kinds of Provider and What to Ask
Different kinds of provider do different jobs. Match the kind to the option, then ask each the same questions. This list is practice, not sourced to any vendor, and it names no one.
Data center migration services range from advice to execution to ongoing operation. So ask every provider the same ten questions.
What is in scope?
Who owns the cutover?
How does rollback work?
What happens to the old site?
Can you share references from an estate of the same size?
What are the exit terms?
How is data protected in transit?
Who is on call?
What are you expecting us to supply?
What is out of scope?
Otherwise, answers given in different shapes are hard to compare.
Data Center Migration Options: Four Mistakes That Skew the Choice
Four mistakes can distort the decision. The first is choosing before the inventory, because without it the answer is a preference. Treating one option as the answer for every workload is another, since a mix can fit better than a single destination. Ignoring lease and support end dates is a third, since these dates set the order of the move. The last is asking providers different questions, so the answers are hard to compare. Our data center migration checklist lists the facility checks to run once you have chosen.
Key Takeaway A choice made before the inventory is complete will be remade after it.
