Move is completed, and looks like it all went smoothly. I basically did
what you suggested here, with a few tweaks:

- hold domains
- synced mailboxes
- updated dns
- then on the old machine, switch the 'local domains' to 'relay domains'
- took off the hold, so that it just delivered all those messages to the
new server.

And now everyone can enjoy the extra bandwidth on the new server! hanks
for the help.
