Data migration between virtual tape systems using tape volser conversion

A computer program product for migrating data from a source virtual tape system to a destination virtual tape system, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to:

• receive, by the computer, a request to migrate data from a source virtual tape system to a destination virtual tape system;
• add, by the computer, to the destination virtual tape system, a destination logical volume having a serial number of a logical volume in the source virtual tape system having the data;
• create, by the computer, an interim logical volume on the destination virtual tape system;
• update, by the computer, a conversion table associating the serial number of the destination logical volume with a serial number of the interim logical volume;
• migrate, by the computer, the data from the source virtual tape system to the destination logical volume;
• and
• in response to completing the data migration, satisfy data access requests using the destination logical volume.

A system, comprising:

• a processor;
• and
• logic integrated with the processor, executable by the processor, or integrated with and executable by the processor, the logic being configured to:
• receive a request to migrate data from a source virtual tape system to a destination virtual tape system;
• add, to the destination virtual tape system, a destination logical volume having a serial number of a logical volume in the source virtual tape system having the data;
• create an interim logical volume on the destination virtual tape system;
• update a conversion table associating the serial number of the destination logical volume with a serial number of the interim logical volume;
• migrate the data from the source virtual tape system to the destination logical volume;
• and
• in response to completing the data migration, satisfy data access requests using the destination logical volume.
