MediaWiki:Movepagetext-noredirectfixer

Moving a page renames it and moves all of its history to the new name. You can choose to automatically create a redirect page that redirects the old name's links to the new name. If you choose not to, be sure to check for double or broken redirects. By moving a page, you are responsible for making sure that links continue to point where they are supposed to go.

The page will not be moved if there is already a page at the new title, unless the latter is a redirect and has no past edit history. This means that you can rename a page back to where it was renamed from if you make a mistake, and you cannot overwrite an existing page.
