I'm sure this works for infoboxes and pretty much anything else in MediaWiki, however, my issue is that I have a template that uses Semantic Forms. The forms also populate an infobox. One of the drop down menus are pulled in from Categories. So I have "Cat 1", "Cat 2", and "Cat 3". So, now I have 1000 pages in MW and on 500 of them I need to rename "Cat 2" to "Category 2". How would I be able to "mass edit" all 500 pages to reflect this change? I'm wanting to do it dynamically, so that I don't have to manually change 500 pages. Is there a way to do this? If not now, is there a way to fix this for future happenings so that I don't make this mistake again?
Any feedback is appriciated.
