MediaWiki:Movepagetext
From Wiskipedia
Using the form below will rename a page, moving all of its history to the new name. The old title will become a redirect page to the new title. Links to the old page title will not be changed; be sure to check for double or broken redirects. You are responsible for making sure that links continue to point where they are supposed to go.
Note that the page will not be moved if there is already a page at the new title, unless it is empty or a redirect and has no past edit history. This means that you can rename a page back to where it was just renamed from if you make a mistake, and you cannot overwrite an existing page.
WARNING! This can be a drastic and unexpected change for a popular page; please be sure you understand the consequences of this before proceeding.
