Hello,

I'm in the process of migrating accounts between two dovecot servers. An old server running ancient 1.0.15 and a new server running 1.2.15. Account migration is going to be gradual and so i would like to use imapsync to move messages and subscriptions from one server to the other. The only problem so far is with POP users. After doing an account migration with imapsync, and although both servers share the same pop3_uidl_format = %08Xu%08Xv, the client downloads every message that was already on the server.

%u means IMAP UID. imapsync can't preserve those. Use either rsync on the filesystem directly or v2.0's dsync.
