BuddyPress.org

The BP site I’m involved was originally set up where users could create their own groups. Now, though, the community and admins have agreed that a reorganization is in order and I would like to be able to merge the forum posts in disparate groups together into a smaller group of admin defined groups.

Here’s a rough example of what I would like to do:
* User-created group 1 (“Educational Games”) + user-created group 2 (“Game mechanics in education”) => one new group (“Gaming and education”), while retaining all of the user activity and posts from both of the original groups.

Is this at all possible without mucking around majorly with the database?
