Power Platform – Restore
The following is an excerpt on restoring Power Platform environments
To restore to a production environment, you must first change its type to sandbox.
Administration mode
You can set a sandbox, production, or trial (subscription-based) environment in administration mode so that only users with System Administrator or System Customizer security roles are able to sign in to that environment.
Administration mode is useful when you want to make operational changes and not have regular users affect your work, and not have your work affect end users (non-admins).
You can optionally disable background operations such as all asynchronous operations including Dataverse workflows and email server-side synchronization.
