Hmm... I'm weak on POP, but I suspect you're out of luck unless you move your clients to IMAP. It will involve an initial download of messages, but once that's done, you should be able to clone between dovecot instances without the clients noticing.
But I think you're coming from another POP server? I don't have the original email any more.
