User blog comment:Iluv80s/will my wiki, made before the overhaul, eventually take on the new look, or will it still look the way it is?/@comment-44807868-20200509054233

Yes, all wikis will eventually switch to UCP; User blog:MisterWoodhouse/Unified Community Platform: The Vision, Purpose, and Process provides more information about the process.

I'm not sure what you mean by "common section", though. Can you elaborate, please?
