We're taking over another company's website and we plan on creating an archived version of their old site using wget
to mirror the site into an archive.example.com website.
Since there are several year's worth of articles and stories and a considerable amount of stories still in Google, we are planning on 301'ing as many of the urls as we can and replacing their old defunct ad code with new DFP tags.
Any thoughts on how to replace thousands of old JS ad tags in a directory full of static html pages?
