There have been extensive changes in web.config between those 2 versions. You probably used the web.config from the old version, which is not supported for that version. What you need to do is to take the web.config (or release.config and rename it to web.config) from the new version, and make the proper changes to that file. This means at minimum:

  • copy connection strings (2x!) from old version
  • copy machine key etc from old version

and, any other changes you made to the old web.config
