Hello all, I am trying to migrate mail from a dovecot-2.0.13-1_129.el5 maildir to dovecot-2.2.10-8.el7.x86_64 centos 7 mdbox. I am using this command doveadm -v -o mail_fsync=never backup -R -u user at domain.com imapc: also tried doveadm -v -o mail_fsync=never sync -1 -R -u user at domain.com imapc: Both work flawlessly - Timo is great !!! - My issue is the source folders are all marked as read. The target folders of-course have unread OK. POP3 UIDLs are also ok (tested for one user). (1) My question is how can I make the source remain same (unread status etc.) so that I do migrate the various domains in a transparent manner and then switch servers ?. I have multiple virtual domains. (2) One more question do I have to do both imapc_ & also pop3c_ migration since I need the POP UIDLs to work properly for my outlook POP3 users after migration ?.
