You could adopt the script for any package you like. The script is
called from the cyrus init script and it does the following:

- It reads a config file which contains the db configs of the currently
installed cyrus imapd binaries. This file is created within the rpm
build process.

- Determine the db format of every db file using the file command, with
an enhanced magics file containing skiplist and possible future
backends.

- Convert db files as needed.

- Write the current db configs to a cache file to prevent big servers
from converting all their dbs on every startup (which is my default).

For more info you may have a look at the source rpm.
