Migrating to the Cloud: What to Plan First
By the CTEKS team · October 15, 2026 · 2 min read
- Define your goals and take inventory first.
- Choose rehost, refactor, replace or retire for each system.
- Plan security, cost and testing from the start.
Cloud migration can reduce hardware headaches and improve access, but a rushed move creates new problems. A little planning goes a long way.
Start with why
Be clear about your goals: replacing aging servers, supporting remote staff, improving recovery or cutting costs. Your goals decide what to move and how.
Take inventory
List your servers, applications, data and dependencies. Some applications move easily. Others need special design, or should stay put.
Choose the approach
- Rehost: move as is, quickest, but may not save much.
- Refactor: adjust the application to use cloud features.
- Replace: switch to a cloud service such as Microsoft 365.
- Retire: switch off what nobody uses.
Plan security and cost
Set up identity, MFA, logging and backup from day one. Estimate monthly costs and review them after the move, because cloud bills reward attention.
Move in phases and test
Pilot with a small group, schedule cutovers outside busy periods and keep a rollback plan. Train staff on what changes for them.
How CTEKS helps
We plan, secure and run cloud migrations for Microsoft 365, Azure and AWS, with testing and support through cutover.
Frequently asked questions
How long does a cloud migration take?
From days for email to months for complex applications. A plan gives you a realistic timeline.
Will we have downtime?
The goal is minimal. We schedule cutovers around your business and keep a rollback plan.
