CC_OLDGEOLITE

The update for csf that was distributed today flags an issue with CC_OLDGEOLITE that was not present in previous versions. "The MaxMind Geolite databases will soon be deprecated, disable CC_OLDGEOLITE to start using the new Geolite2 databases" How does one go about disabling CC_OLDGEOLITE and what implications are there to doing so? My clients use several MySQL databases but nothing else.
