When you are trying to Migrate .net 1.1 to .net 4.0, please separate your project in different folder there should not be duplicacy of project or backup, if backup is there cut and paste some another place, once you migrate then check your sin or csproj file conversion done or not, then open the project and rebuild it, please refer below link that would be helpful for you.
