I created a wiki page, limited the permissions to one group, moved it. Now, when accessing the old URL, I see `This document has been moved to /w/…`. I click `Edit Document` and change permissions to `All Users`. Upon saving changes `A moved document can not be deleted.` is displayed in red.
What I would actually like to do is clean up the old wiki page in a way such that the URL can be used anew when someone deems it necessary, without seeing the old content (or title) and without being hindered by any permission issues.
