I have read the https://doc.dovecot.org/2.3/admin_manual/migrating_mailboxes/#id7 and there is one part which is not 100% clear to me. We have 2 Dovecot servers mail1 (2.2.36.4) and mail2 ( 2.3.21 ). Now I have understood that I need to add this to mail1 service doveadm { inet_listener { port = 12354 } }   doveadm_password = supersecret and this on mail2 doveadm_password = supersecret The question is for me now: I think that this command doveadm backup -Ru username tcp:host:port should be executed on the mail2. Is this assumption right? Yes. What I also found is that on that Page https://doc.dovecot.org/2.3/admin_manual/doveadm_mailbox_commands/ the wiki is linked for the manpages but the wiki link shows this. The old wiki has been closed Our primary documentation is now at https://doc.dovecot.org, please update your links. What's the right link for the manpages https://doc.dovecot.org/latest/ Best regards Aleks Aki
