Cyrus and Dovecot use differen structures to store the mails and
meta infos on disk. Cyrus is not able to pares the Dovecote data
and as far as I know dovecote can't parse the cyrus structures
either directly. There might be tools to convert the data. Most
tools I know of use the IMAP protocol which requires a running imap
server that can access the old mails.

If i remember correctly the dovecot data files use the mbox format.
There are some tools that can upload mails from mbox files to IMPA
Servers. But i don't know if it is possible to convert all mailbox
features with them (ACLs, seen status for shared mailboxes).

Regards,
