• Configuration and secrets are migrated safely.
• Network, DNS, certificates, and ingress are ready.
• Observability exists in the target environment.
• Capacity and quotas are validated.
• Security controls match or improve current posture.

Data and state

• Data migration or synchronization plan exists.
• Reconciliation queries are defined.
• Backup and restore plan is tested.
• Caches, indexes, queues, and derived data are included.
• Rollback or forward-fix path is documented.

Cutover

• Cutover owner is named.
• Go/no-go criteria are defined.
• Rollback trigger is defined.

• Post-cutover validation steps are documented.
• Cleanup plan exists for old resources, credentials, and alerts.
