Don't forget to update any copygroups that may have a DESTINATION= of a DLT tape pool...
If you can afford, and are not in a hurry, just point all the new backup data to the SDLT tape pools and leave the old DLT tape sitting there. The data will start to go away with expiration and after a time period, like your retention policy for the domains, move the remaining data to the new SDLT pools with the MOVE DATA STG= command. If there's no hurry to get the data moved over, just leave it alone for a while. Then move it. Less data to move.

Your storage pool backups will make the trip as the data moves to the new tape storage pools, freeing up your off-site DLT tape. My move took about two weeks from the start, for about 480 DLT tapes to 120 LTO; part of the time-delay was allowing some 8 and 10 day retention archives to just die a natural death in DLT format.
