Question Reverting to old Factions

Hello! I recently started a Factions server with the new factions plugin. A lot of player, and myself, dislike the new plugin. Is there a way to revert to the old version while keeping all faction data? Also, how do you get the older version to run? I am talking about MassiveCore's factions plugin by the way.

(If this is in the wrong place, I wasn't sure where to put it)

Thanks,
Sade
