Well, I just saw Cyrus 1.6 -> Courier converter. See if it works with
2.0:

It doesn't seem to preserve UIDs directly, but it shouldn't be too
difficult to fix to do that.

And what do you mean about UIDL? POP3 UIDs? Cyrus 2.1 seems to use the
same algorithm than Dovecot (uidvalidity.uid), except if pop3_new_uidl
isn't set it uses just uid which I think isn't a good idea to keep
using.
