Discussions is, in many ways, the feature succeeding the forums, but they are built completely separately. That's why forums don't "upgrade" automatically to Discussions.

If you are an admin on a community that doesn't have Discussions yet but would like to, you can just let me know, and I'll enable the new updated Discussions for you. In that case, the wiki's forums will still be there for the time being, and you'll have two social areas (unless you'd like us to remove the forums and all the posts they contain in the process).
