I received this error at the end of a migration from imapc to mdbox. Is it because I wanted doveadm 'sync' instead of 'backup'? I didn't get time to do any testing, but since you're pushing for the release, here it is:
kerio2:~ adminuser$ /opt/dovecot/bin/doveadm -o imapc_user=jsample -o imapc_password=****** -o imapc_host=*.*.*.* sync -R -u jsample_dc@mydomain.com imapc:/tmp/imapc dsync(jsample_dc@mydomain.com): Error: Can't update mailbox Archives/2011: Not supported
Yes, it's because of "sync". The "Not supported" comes from imapc backend, because Dovecot tried to do some changes to it that weren't possible with IMAP protocol (modseq changes probably). I think the migration still was successful though.
