Ah yes, sorry.
 * You go on the page you want to delete/move.
 * There is a blue bar in the down of your screen.
 * You select "My Tools", "What links here"
 * You'll have all the pages linking to the page, and you have to change the links.

If you a whole universe to rename and it's (almost) just a problem of reality designation (cf. Age of X), you can change many links in the same row on the page.
