Other things you should take care of

 - you must copy or recreate alias/virtual maps for postfix (see genaliases)

 - while the change to your DNS is propagating though Internet caches, 
messages will go partly to mm and partly to lx5.  This means list archives on 
lx5 could have some hole and people could experience some temporary glitch 
(e.g. confirmations requested on mm but the response received on lx5).  Try 
to keep refresh time to a short value during the switch, and/or shut down 
postfix on mm so that messages will be kept queued until sent to lx5.
