The cvt_cyrusdb_all script is only part of my cyrus-imapd rpms, it's not
part of the cyrus-imapd distribution or other packaged distributions.

IIRC there is another possible problem with Berkeley db logs still beeing
around after a conversion to skiplist. In that case I think the files in
can be deleted before starting cyrus-imapd. However, always be sure to
keep backups of all files in a safe place.
