Two methods to migrate data are:

v Use the IBM Tivoli Storage Manager server MOVE D ATA command. This

method allows the legacy ACSLS data to move to a new storage pool without
moving any expired files in the aggregates. For more information, see the
Managing Storage Pools and Volumes section of the Administrator’s Guide.

v Use the IBM Tivoli Storage Manager server storage pool reclamation function.

This method works by reclaiming the active files from the legacy ACSLS storage
pools. Reclamation processing, however, is very resource intensive and should
be performed during periods of little activity on the server. For more
information, see Reclaiming Space in Sequential Access Storage Pools section of

the Administrator’s Guide.
