/var/lib/imap/tls_sessions.db
/var/lib/imap/deliver.db

Yes, convert the files like this:

su - cyrus -c "/usr/lib/cyrus-imapd/cvt_cyrusdb /var/lib/imap/deliver.db
berkeley /var/lib/imap/deliver.db.skiplist skiplist"
mv /var/lib/imap/deliver.db /var/lib/imap/deliver.db.berkeley
mv /var/lib/imap/deliver.db.skiplist /var/lib/imap/deliver.db

the same for tls_sessions.db.
Then, edit /etc/imapd.conf and start cyrus-imapd.

Anyway, if something fails, deliver.db and tls_sessions.db are not really
very important so you could even remove those db files and let cyrus-imapd
start with new empty ones.
