Migration order

1. Export or sync the code into a controlled repository.
2. Identify framework, build command and runtime requirements.
3. Create separate production environment variables.
4. Deploy to a temporary target URL and run core flows.
5. Move the custom domain only after auth callbacks and webhooks are updated.
6. Enable errors, uptime and rollback checks.

Do not forget

Database, storage and scheduled jobs may remain on other services. A frontend deploy does not migrate data automatically.
