Pretty sure you are using -f incorrectly. Try this:

sudo -u cyrus /usr/lib/cyrus-imapd/ctl_mboxlist -d > 
/var/spool/imap/mailboxes.db.txt

  on the old followed by a transfer of /var/spool/imap/mailboxes.db.txt

  to the new followed by:

sudo -u cyrus /usr/local/cyrus/sbin/ctl_mboxlist -u < 
/var/spool/imap/mailboxes.db.txt

on the new
