after I tested a server migration in my testserver environment I have a some
last questions:

1.) When I successfully migrate a server with the migration wizard, is it
still possible to go the way back: Turn off the new server and turn on the
old one? Could I still use the old server with the old data? In my last
tests the old server started up but I could log in. DSrepair didn't help.

2.) Is it better to migrate all the data from the old server to the new
server (via network with the migration wizard) or get the data back from a
storage device (Tape)?

3.) Is there a simple way to find out the server id? (The number given to
the server on the installation)

Thanks for the answers...
