"netstat --listen --tcp --numeric --program"

Somewhere along the line some distributions changed the SIEVE port.

Stop the new server
Rsync from the old server
Start the new server 
Make sure everything is working on new server
Stop the new server.
Stop the old server.
Rsync again.
Start the new server.

pretty quick as it will only grab the few changed items.
