I use the following script to move volumes from one partition to another. It
works quite fine BUT I TAKE NO RESPONSIBILITY FOR ANY DAMAGE!
It looks for RO and BK volumes at the source side and restores them at the
destination side, too. Therefore the volume move is done on all "depending"
volumes, not just the original RW volume.
