I don't think so.  The sync happens via IMAP, and I don't think IMAP
clients can *set* UIDs of messages; only the server does this (someone

Yes; at least, it has for us in testing (with Dovecot as the destination
server.)  Whether it will work for you depends on the specifics of the
source server.  Why not give it a try and see?
