what I've done just yesterday is:

on the new box:
format log and db volumes
restore most recent full dbbackup
copy over start/stop scripts and dsmserv.opt

old server:
stop and start with 'DISABLESCHEDS YES' and 'NOMIGRRECL' in dsmserv.opt
disable sessions
empty out all disk and file volumes
delete them all
make incremental dbbackup
halt old server

new server:
retore incermental on new box (commit=yes)
start tsm on the new box
recreate disk and file volumes

We usually only do full dbbackups, so I had no intermediate incrementals...

If you empty out all you disk/file volumes before you restart your
server, your downtime might be as short as one incremental backup and
one incremental resore, minutes....
