You should be able to use Bacula's migration feature to move jobs on an 
old volume to a new volume on the vchanger autochanger. Check the 
Migration and Copy chapter of the Bacula Main Reference. This will 
require a new pool for the vchanger volumes. Volumes in the old pool 
will be moved to vcahnger volumes in a new/different pool. Once a volume 
is successfully migrated to the new volume, the old volume can be 
deleted and its space reclaimed. In other words, it is the same as 
migrating a disk volume to a tape volume. After all of the volumes are 
migrated, then change the client Jobs to use the new pool and vchanger 
storage.
