Swapping pages is nothing more than a bit of creative moving of the pages, so, you would use the steps laid out in the last exercise here. We will use three different pages here; page 1 is our page titled Installing MediaWiki, page 2 is our page titled The Installation of MediaWiki, and page 3 is our newly-created page which we will call Temp.
1. Create a new page. This page will be a temporary placeholder so you can name it something like Temp.
2. Move the first page, in our example this will be Installing MediaWiki, to the Temp page, page 3.
3. Delete page 1, Installing MediaWiki.
4. Move page 2, The Installation of MediaWiki, and rename it Installing MediaWiki. This is allowed as we deleted the old version of page 1.
5. Delete page 2.
6. Move page 3, Temp, to page 2, renaming it The Installation of MediaWiki.
7. Delete page 3.
When you are done, the tutorial should now be named Installing MediaWiki and the page describing the installation process...
