}'- **Validate readiness:** Confirm capacity, quotas, security controls, certificates, secrets, dependencies, and compliance requirements in the new region. - **Protect data:** Take verified backups; validate replication consistency, encryption, retention, and restore procedures before cutover. - **Test end to end:** Run load, latency, failover, integration, and smoke tests using production-like traffic and data. - **Control cutover:** Lower DNS TTLs, deploy gradually with canary traffic, freeze risky changes, and monitor errors, latency, saturation, and data integrity. - **Prepare rollback:** Define go/no-go thresholds, owners, communication channels, and a rehearsed rollback plan; retain the old region until stability is confirmed.
