In my experience mailutil handles this fine.

I've had excellent results with mailutil, as suggested earlier by Ken 
Murchison. I used it for the original migration from MDaemon3 on WinNT 
over to the shiny new Cyrus box (and what a pleasant change, too...). I 
found it very good, and it made my migration quite simple.

On the other hand, if you're moving from Cyrus 2.1 to 2.2 is it possible 
to simply copy the mail spools and configdirectory across?
