Wikipedia:Tips/Moving pages

Moving pages Some pages do not have the right title. Either it does not follow Wikipedia's naming conventions, or it has simply been misspelled. You can usually move a page to a new title by clicking on the move tab at the top of the page. This preserves the edit history by transferring it with the page, and is much preferred to "cutting and pasting" the text to its new location, because this leaves the history behind. The talk page, if any, will normally be moved as well. When a page is moved, a redirect is created at the old location, so please fix any double redirects that result.

Moving a page in this way is not possible in some cases, such as when a page other than a fresh redirect exists at the destination, but you can ask for help at Requested moves.
