One other thing to consider during the upgrade is how you rollback in
the case that you run into some serious bug w/ v6. With the in-place
upgrade you need to restore the TSM database before you're back in
business (I've done this before - it works, but is a little harrowing).
If you bring up a new server alongside your old server, all you have to
do is switch clients to use the old server while you work on the new server.
