Ah, I knew it, that's why I asked. Please let non *x OSes out of the game.
Use either rsync of tar. Something like:

on oldbox:

cd /
tar cpzvf /tmp/cyrus-imapd.tar.gz /etc/cyrus.conf /etc/imapd.conf
/var/lib/imap /var/spool/imap
scp /tmp/cyrus-imapd.tar.gz newbox:/tmp/

on newbox:

cd /
service cyrus-imapd stop
rm -rf /var/lib/imap/* /var/spool/imap/*
tar xzpvf /tmp/cyrus-imapd.tar.gz
service cyrus-imapd start
