Depending on what software you are using, you could do a search. I use Homesite for some of my development, so I would run an Extended Search operation on the entire set of pages, and then check anything it found. If there were a lot, I'd also use Extended Replace instead of making the changes manually.
If you have the pages all in one folder, you could also use grep. You could probably also run Xenu on your site and see what it finds, then fix any links that it discovers.
