That's a little surprising in view of the upgrade instructions at
http://cyrusimap.web.cmu.edu/imapd/install-upgrade.html

Although they appear to be for 2.3, they seem to imply big changes in
the default database format (from db to skiplist) for some files at the
2.1/2.2 boundary.

I'm glad to hear that no special conversion action is required, though I
wonder if that's too good to be true.
