One of those cyrus.* files should contain the max UID - I can't remember
which. If you can restore/copy that across, it should (I think) number
any new messages starting from there. Then you can restore/copy the
original messages across later.
I've never tried this before, so I may be getting it wrong. Hopefully
someone with more in-depth knowledge of Cyrus can comment.
