Cloud Migration Checklist: What to Do Before You Move
Migrating to the cloud — or between cloud providers — is one of those projects where good preparation is the difference between a quiet, uneventful switch and a stressful one. A few things worth confirming before you start.
Know exactly what you're moving
A full inventory of applications, databases, files, and dependencies sounds obvious, but incomplete inventories are one of the most common causes of migration surprises — something gets missed, and it's discovered only once it breaks.
Have a real backup, not just a plan for one
Before any migration begins, a full, verified backup of everything being moved is non-negotiable. "Verified" matters here — a backup that hasn't been tested for restore isn't a reliable backup, just an assumption.
Plan for downtime honestly
Even well-planned migrations often involve some period of downtime or reduced availability. Deciding in advance when that's acceptable — and communicating it to anyone affected — avoids the migration itself becoming the source of a bad customer experience.
Understand the new cost structure before you move
Cloud pricing models can differ significantly from what you're used to, and costs that look reasonable in a sales pitch can look different once actual usage patterns are billed. Estimating realistic costs before migrating avoids an unpleasant surprise on the first bill.
Test in a non-production environment first
Wherever possible, migrating to a staging environment first — and validating that everything works as expected — catches problems before they affect real users, rather than during the live cutover.
None of this eliminates risk entirely, but a migration planned around these basics is far more likely to be the non-event it should be, rather than a scramble.
