i agree,
You must make sure you have the correct crystal report assemblies installed on your new server.
However, there is one thing. As far as I am concered, Windows Server 2008 R2 has limited support on Classic ASP or older ASP.NET version. I don't know whether this is true, but you run Classic ASP on Win 2008 R2, I always have to tweak something on the server
