So we had over 1,000 blog posts published, each of which contained an mp3 file of our daily podcast. Those are all intact and it was one of the main focuses of our migration. Our contractor affirmed they had some sort of automated process for doing this.
We now realize some corners of the site were missed, and we missed them too in our double check afterward. It's about 55 dead links, made up of various uploaded docs or mp3s.
One time in the past when we found a couple of these, I just reactivated our 7.0 site to grab the files, because they still existed there when you click those links. Then I'd go to the dead link on our 7.1 site and reupload them.
55 really isn't the end of the world and I can do it manually, I was just curious if anyone knows of a better system for this. I assume any automated system costs or requires plenty of set up on its own, but I'm happy to be proven wrong.
Thanks!
