First, you could check the dovecot mailing list to see if someone has done 
this:

One idea that comes to mind is to set up a temporary box running Dovecot 
and drag your messages in your client from one server's folder to the 
other's, letting the client do the work using the IMAP protocol. You can 
even do this using the mailutil utility that comes with the UW-IMAP 
package. It uses IMAP protocol to copy or move folders.
