I'm getting a little confused by the dual use of "cluster" for both Ceph and OpenStack. Are both pools in the same Ceph cluster? If so, could you just clone the image to the new pool? The Nautilus release also includes a simple image live migration tool where it creates a clone, copies the data and all snapshots to the clone, and then deletes the original image. > But that would be slow and duplicate the data which I'd rather not do.
