We are preparing to change shopping carts for our site. We have created a database and script to redirect old URLs to new ones, where needed. Before we transition the new cart to the live server, I would like to check to make sure there are no links that have been missed.
I thought about using Xenu to crawl the old site then changing the hosts file to redirect the requests to the new one....but I don't see how to recheck links in Xenu.
Is there a way to do that or an easier way to check for future 404 errors?
