If your site has multiple DSA domains, the BAR admin user can export metadata from DSA domain A and import it later to DSA domain B using the DSA CLI. This migration is performed for each job and is necessary before any restore operation can be done on the target DSA domain B. As part of the migration, the administrator is responsible for transferring the related information for the NetBackup catalog for DSE operations. For DSU, the administrator is responsible for the management of related files on the disk file system.
