Not all wikis are moved yet. They're still in the process of migrating, and CC will be last.

There's lots of reasons for that. CC is the controller for other wikis, and it's holding up the other legacy wikis until they migrate. Additionally, CC was the last wiki to move from wikia.com to fandom.com, it was last to move from Forums to Discussions, and it will be last to move from Legacy to UCP. That's simply how it's done.
