Thank you for the link, unfortunately I am missing the crucial clue. I get the directories backed up, but I don't get them imported properly.... all mails are displayed as unseen. i tried with simple pasting and the doveadm import command. Is there a trick to preserve the flags? Maybe it is because the old dovecot server uses short username without the @ and the domain name and the new one uses the mail address to identify the user.
