  When I did it I had the 2 servers running at the same time for a while 
so I could move data from old to new using an nfs mount.  This took a 
few hours to move approx 100 Gb.  Of course I did this with smb off on 
both machines.  Then I stopped the old server, changed the name and ip 
address of the new server, and continued as you outlined.
