To give an article a new title, it has to be "moved": The page must be copied together with the talk page and all versions into a new file.
The old file is initially retained and is replaced by a redirect to the new page.
- Go with your mouse in the upper bar and click More
- Select Move
- Select the new file name (Please don't use special characters!)
- If the article should be moved in a particular namespace, select the intended one
- A brief rationale for renaming helps other colleagues to retrace your step.
