Open the vault and export every file you intend to preserve. Verify representative exports independently.
Confirm required backups, synchronized copies, and recovery records. Lock and close the vault, then quit active processes.
Identify all obsolete vault copies and their backup retention requirements. Remove them only after the replacement data and recovery plan are tested.
Deleting a vault can be irreversible. Do not remove the last accessible copy because a new empty vault was created.
Retire credentials and recovery material according to your security policy after all required data is safely migrated.
