Abstract
A computer-implemented method, in accordance with one embodiment, includes receiving a request to migrate data from a source virtual tape system to a destination virtual tape system. A serial number of a logical volume having the data in the destination virtual tape system is added to the destination virtual tape system. An interim logical volume is created on the destination virtual tape system. A conversion table associating the serial number of the logical volume is updated with a serial number of the interim logical volume. The data in the logical volume is migrated to the interim logical volume. In response to completing the data migration, data access requests are satisfied using the logical volume.
