Moving Cyrus IMAP users from one machine to another?

I had an overly upgraded Mac OS X Server set up (10.0 client > 10.1 Server > 10.2 Server > 10.3 Server > New Drive with Carbon Copy Cloner). Needless to say it had its share of issues as a result, so earlier today I used a spare machine to start a new clean install. I got everything moved over to the new machine, but I hit a major setback when trying to move the IMAP users over. There's nothing really in any of Apple's docs about this, so I'm at a loss as to what to do. My first attempt had me having to reinstall the the OS again since I managed to overwrite some critical piece of the Cyrus environment, and like to avoid doing something stupid like that again. :-) Any tips?
