PRACTICAL CHECKLIST
The PostgreSQL migration checklist teams can reuse
A reusable migration checklist covering preparation, transfer, validation, cutover, cleanup, and post-migration review.
A repeatable checklist makes database movement less dependent on memory and less vulnerable to rushed decisions.
Before the migration
Confirm ownership, maintenance windows, source access, destination capacity, expected table count, and a tested recovery position. Record the target state before work begins.
During the migration
Track each stage: source verification, backup creation, artifact validation, destination preparation, restore, destination validation, and cutover readiness. Keep progress separate from customer-facing secrets.
After the migration
Confirm application connectivity, inspect representative queries, preserve the source according to the agreed safety window, and remove temporary artifacts and secrets when the workflow is complete.
