A successful migration is not just “copy the files and wait”. It is a controlled runbook.
Before the move
- Lower DNS TTL in advance
- Create full backups of files and databases
- Record service versions and dependencies
During the move
- Enable maintenance or write restrictions
- Perform the final database sync
- Verify panels, email, cron and SSL
After cutover
- Watch logs and 4xx/5xx errors
- Keep the old node available for rollback
- Check integrations and webhooks
The simpler and better documented the migration plan, the fewer surprises you get after the switch.
