I can think of a few ways to do this: 1. Use imapsync 2. Use Cyrus replication (just a guess) 3. Use Cyrus Murder clustering 4. Use Rsync into 2 different partitions on the new server Imapsync is not a bad option. Write a script to fire off multiple imapsyncs at once. Run it to completion. Then run it again. Then run it again. Schedule your outage. Run imapsync every night up to the day of your outage. Block your users from accessing Cyrus, run a final imapsync, then stop Cyrus on the 2 old servers and start using the new server.
