Yes, indeed.  We (Freie Universität Berlin) published our Cyrus2Dovecot
just a few days ago.  Unlike the older script, ours _does_ try hard to
preserve all available metadata, and this should actually work with all
Cyrus versions (tested with both the oldest and the newest available
Cyrus release, that is, 1.4 and 2.3.12p2, and with various database
formats).  Apart from that, ours provides a few additional features we
needed for our conversion which might also be useful to others, such as
renaming (or moving) folders using s/regex/replacement/ substitutions.

We now added our Cyrus2Dovecot to the wiki page.
