US Patent 11372733 Mount and migrate

Systems and methods are disclosed for migrating or restoring a server database such that the migrated server database can be used before data has copied to storage for the migrated server database. Data used by a server database is copied to a copy storage, which is mounted to a second server database. The second server database is brought online using the copy of data. The copy of data is copied to a second storage. The second server database is brought offline and switched to run from the second storage. The second server database is brought back online, thereby permitting use of the second server database before copying data to the second storage.
