The client's IP address is saved as part of the node definition (do a q
node f=d and you'll see it.), so that isn't a problem.

However, test the move on ONE client before you flop the IP addresses. 
All the client data will move fine with an EXPORT, but it used to be that
if your server platform changed, the client password wouldn't work

Never got a real explanation of why, something about the way the password
gets encrypted.  Don't know if it's still an issue, but I ran into it a
couple of versions ago going from an AIX to a Windows TSM server.
