I know this guide but last time i had to upgrade between 1.2 to 2.0 it
was totally a mess, as

doveconf -n -c /etc/dovecot/dovecot.conf > dovecot-2.conf

didn't output anything.

additionally, this is for upgrading, but what about mailbox migration
(via rsync)? Dovecout would preserve the UID and anything else to
avoid a new download on clients?
