I’m trying to migrate mdbox to maildir based on https://wiki.dovecot.org/Migration/MailFormat
I have modified dovecot.conf and set mail_location=maildir:/tmp/destination/mailboxes/
Then I had run
/mnt/testmail/bin/dsync -Dv -u user@domain.com mirror mdbox:/source/mailboxes/user@domain.com
but that did nothing. Then I have modified dovecot.conf and set mail_location=mdbox:/source/mailboxes
Then I had run
/mnt/testmail/bin/dsync -Dv -u user@domain.com mirror mdbox:/tmp/destination/mailboxes/user@domain.com
that copied over user@domain.com mailbox from the source to the destination location. As that was working I have tried to run
/mnt/testmail/bin/dsync -Dv -u user@domain.com mirror maildir:/tmp/destination/mailboxes/user@domain.com
but that got an error:
dsync(user@domain.com): Debug: Namespace inbox: type=private, prefix=, sep=, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:/mnt/testmail/mailboxes dsync(user@domain.com): Error: User initialization failed: Namespace '': Unknown mail storage driver maildir
First problem is that, based on example #2 from above, provided syntax in https://wiki.dovecot.org/Migration/MailFormat is incorrect or for some reason is not working for me as it should for example #1.
Second issue is not recognizing maildir format – what about that? Docecot has some missing libraries?
Dovecot version 2.2.18 and config looks like:
# 2.2.18: /etc/dovecot/dovecot.conf
# Pigeonhole version 0.4.8
# OS: Linux 2.6.32-754.14.2.el6.x86_64 x86_64 CentOS release 6.10 (Final) xfs

Highly possible it was custom compilation.
