User blog comment:MisterWoodhouse/Fandom is upgrading to a modern version of MediaWiki/@comment-34888194-20190620152134/@comment-1824272-20190620183746

This was the plan a while back, but this has been put on hold indefinitely while Discussions evolves into Community Feeds and it gets more developed. AFAIK this MediaWiki upgrade project has nothing to do with migrating Forums to Discussions/Feeds, but of course staff may announce otherwise.
