The Administration Console Change Center provides a way to lock a domain configuration so you can make changes to the configuration while preventing other accounts from making changes during your edit session.
The domain configuration locking feature is always enabled in production domains. It can be enabled or disabled in development domains. It is disabled by default when you create a new development domain.
After you finish
When you enable domain configuration locking, you must use the Change Center to lock and edit the domain configuration. See Use the Change Center.
