• OK, I think I finally got this running again! 😀

    After my last post I went to the ReportServer DB and noticed that I had one record in the Keys table for the server that Report Server is running on. I thought that this might be the key from the old server so I deleted it. As soon as I deleted this and restarted both IIS and Reporting Services service, everything just worked!

    Hopefully this may help someone else that runs into this situation down the road.
