I found this http://community.wikia.com/wiki/Help:Category#Advanced_notes

"Category pages cannot be renamed - this is to avoid confusion, as renaming a category page would not change the category on the pages contained within. To rename a category, the category must be changed on all the pages within it"

So yeah, Strong... That's going to take some time.
