Ok, so I have used my brain and came up with that:

• Created new directory and copied over original dovecot to that location as /tmp/destination
• Spawned that dovecot as dovecot-test
• Modified dovecot.conf and set mail_location=maildir:/tmp/destination/mailboxes/
• Then I had run

/mnt/testmail/bin/dsync -D -v -u user@domain.com mirror mdbox:/source/mailboxes/user@domain.com

based on description from there: https://wiki.dovecot.org/Migration/MailFormat but first that doesn’t do anything (/tmp/destination/mailboxes is empty) and on another hand I don’t think so dsync is reading modified dovecot.conf as is not creating maildir format mailbox converted from mdbox format provided as the source location.

Thoughts?

I saw that before but there is only maildir -> mdbox but not mdbox -> maildir

Did I have missed anything there?

There is no direct example on how to do just that but you can use your brain and modify the mbox -> maildir example a bit.
