After a full Backup Stgpool to your new copy storage pool I would simply delete
the volumes in the old copy storage pool and then the old stgpool itself.
There's no need for machinations in dealing with the data in the old stgpool,
as you're covered with the new copy, and the old one is a now-pointless second
copy.
