Can you simplify the process by doing a one-time backup to some other
media?  For example:

+ On new box, Make a filesystem /tsmcomm/dbbackup
+ NFS export the filesystem.
+ Mount it on old system on the same path
+ Make new devclass, type FILE, pointing at that path
+ do a DB backup
+ copy volhist to new place
+ do whatever restore/upgrade chicken dance is required.


You can unzone all the tape devices from the new box to avoid the risk
of new-box dinking with the volumes before you want it to.

This might even let you work through the process several times in a row
as dry runs.  _highly_ recommended, that.  In the 6.1 and 6.2 betas, I
had to do several dry runs each time before I got a process I was happy
with.
