"doveadm backup" wants to delete and recreate a folder if there are
some changes that can't be incrementally just added to it (mainly if IMAP
UIDs would need to be inserted in the middle of the folder). Maildir doesn't
allow INBOX to be deleted (because it's difficult), so this fails. Solution
is to either not use Maildir format, or rm -rf Maildir manually before running
dsync.

Hi Timo, hi all!
The problem is that I'm removing all .maildir/ folder before starting
dsync. This solution doesn't work for me. Do you think that only
migrating to e.g. mbox and then migrating from mbox to maildir is the
only way that can works?

Thanks,
Marcin

Hi all!
I've found what was the root of problem. I removed .maildir/ but I
didn't removed index files.

Thanks,
