Creating dovecot-uidlist then caused the UIDVALIDITY to change, which causes IMAP clients to redownload all messages, and as you can see Dovecot doesn't handle UIDVALIDITY changes all that nicely. v1.1 does a better job with it though.
So, is there a way to migrate WITHOUT all my pop3 users re-downloading everything?
Well, what you just did probably did that. It just caused IMAP users to download the mails again, but that's more transparent to users because it doesn't create duplicates.
I did think about adding the possibility of storing POP3 UIDLs to a separate field in dovecot-uidlist for v1.1, but I haven't managed to write that code yet.
