Map the current state
List systems, databases, integrations, DNS, certificates, scheduled jobs, backup, and monitoring. Also write down who owns each part. The goal is to find dependencies before they become incidents.
Include both technology and business context. A server may be easy to move technically but difficult to shut down at the wrong time.
Plan testing and rollback
Decide how you will verify function, performance, permissions, and data after the move. Also document when you abort and how you return if something does not work.
A rollback plan is not a sign of uncertainty. It reduces stress and makes decisions easier when time pressure appears.
Make handover explicit
Once the environment has moved, operations must take over: monitoring, backup, support paths, and contacts. Decide what is checked during the first day, first week, and after the first month.
This final part often decides how the customer experiences the migration. A stable handover turns the project into operations, not just a move.
