Before you begin
Confirm the latest working code, required credentials, external services, and rollback path.
Keep the current production environment available until the new release is verified.
Use a controlled deployment process
A custom domain makes the app feel real, but it should be one of the last launch steps.
Before connecting it, confirm
The production build is the version you intend to release
Login and permissions work
Required data connections use production-safe credentials
Errors are logged
A person knows how to roll back
The old app or page will not be disconnected too early
Email, analytics, and external callbacks use the correct domain
Privacy, terms, and support links are present when required
For a migration, keep the current app live until the new domain path has been tested. Then schedule the switch, verify it, and retain a rollback option.
A domain change should be boring. The important work happens before the switch.
Common mistakes
Pointing the domain before the application is tested in production conditions.
Forgetting SSL, DNS propagation, redirects, and authentication callbacks.
Removing the old environment before the launch is stable.
Frequently asked questions
Can I keep my current app live during deployment work?
Yes. A separate environment, copy, or branch lets you test the new version while the current application remains available.
What should a rollback plan contain?
The prior working version, the data and configuration changes involved, the person authorized to roll back, and the conditions that trigger the rollback.
