• So its the Report Manager URl you are getting the error on?..

    (IE. http://blahblah/Reports)

    Have you tried the reportServer URL (looks like a basic FTP interface (text))

    (IE. http://blahblah/ReportServer)

    Any errors showing is RS Configuration Manager?

    You should find the Web.config for Report Manager here:

    <Installation directory> \Reporting Services \ReportManager\Web.config

    You may have an assembly reference to Oracle from the 2008 version that you'd need to remove. Not sure yet though. If you can post its contents *and backup before making changes*
