--> Do this via mgmt. class updates (don't forget to activate them) and
maybe set
maybe set
the volumes to read-only as well.  Or better yet rename the current storage
pool to
"old" and give the new storage pool the old name, thus no mgmt. class
updates.
All backups will be incremental.

--> Wait as long as you can to do this.  The longer you wait the better off
you will
you will
be since you will have a smaller amount of data to move.

--> no problem after the move data is done.  You don't have to wait for the
entire
entire
set of moves to complete...you can do a tape volume at a time if you want:
move data, delete volume, etc...
