Mass duplication of images from 1 pool of tapes to another

Hi. I'm running a 5230 appliance that's connected to a tape library. And I need to duplicate images from approximately 700 tapes to another set of tapes (in the same environment). I know this can be done via the NB gui in the catalog section, but is there an easier way? To put it mildly, doing checking each tape to get a backupid, searching for each one individually in the catalog and duplicating them one by one seems crazy.

Thanks in advance,

Larry
