Yes, I would 'leave' the domain and then give it a new IP and possibly a 
new hostname (depending on what you are going to call the new Unix 
domain member). You could then re-join the domain.

Now prepare your new Unix domain member, join it to the domain and then 
copy the required data from the old machine to the new machine. Once you 
have transferred everything from 'old' to 'new', you can 'leave' the 
domain on the 'old' machine and turn it off.
