I installed the cyrus packages before transferring any data between
servers. I then shut down cyrus on the new server and started rsyncing
the data.

I've only used imapsync for moving mailboxes from Lotus Domino to
cyrus. Domino is slow serving imap and it took longer to imapsync the
same mailbox from Domino to cyrus then rsync it from 32 bit to 64 bit
cyrus machines. I would think that imapsync would be slower because of
all the imap communication overhead. The advantage of imapsync is that
you don't have to shutdown either system.
