In my test case I hadn't any problems with seen and other flags.

To be honest this server is an IMAP only service, so I haven't tested the POP3 cases. Anyway I think that this problem is related with the first one, because if a message is downloaded via POP3 the server sould set the seen flag on it. I did a public cyrus server migration months ago from 2.2.x to 2.4.17 and I don't recall to have had thoose kind of problems (and I'm sure that there where 30/50 users using POP3 with copy on server). Did you rsync the /var/lib/imap/user/ from the old server?
