	This is basically the sort of thing that I'm doing for ntp.org.

	My plan is to set up the new machine, copying all the 
configuration information from the old machine, but not populating 
the list or archives just yet.  Do a test for each list to some 
addresses I own, making sure that the behaviour is as desired with 
regards to how the list reacts when a subscribed or unsubscribed user 
posts.

	Once proper behaviour is confirmed for all lists (including 
USENET news gateway features, but posting to a suitable ".test" 
newsgroup instead), then copy the subscriber lists over for all 
lists.  Shut down the mail servers on both the old and new systems, 
so that nothing comes in while you're moving things over.

	Set up aliases on the old server to the addresses on the new one, 
so that all mail for those lists are forwarded to the correct place 
(just comment out the old alias entries, in case you need to restore 
the previous behaviour).  Once complete, copy the archives over and 
set up similar internal redirects within the web server, so that 
incoming browsers are redirected to the correct place.  Keep an eye 
on things for a while.

	Once we're satisfied, then change the DNS records so that the MX 
and IP address point directly to the new server.


	At least, that's my current plan.  However, I will also closely 
review 
<http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq03.004.htp>, 
and then see if there are any other additions/changes that need to be 
made.
