Well, Jim recommended a very safe way to do it. I normally do one of
two things:

1. If I really trust the intermediate network I run telnet to do the
upgrade, and shut it off when I'm done.

2. ssh forks off each connection so I log in do the upgrade. Carefully
kill all the session besides my current session, and reload ssh. If
I can log in to the new server then I close my current session.  Otherwise
I try to figure out what is wrong, and try again.

Even we with the second method you might want to startup telnet just in
case as a precaution.  I'm sure some would recommend using rsh with a
.rlogin so that if you do need to use it you can get around sending 
passwords over the wire.
