VS2010 Upgrade from VS2008 compile Error

Question

So recently at work we upgraded our project from 2008 to 2010 what gets deployed to our web server compiles fine but what is being compiled for our app server is failing. The error we see is:

Solution file xxx.sln is from a previous version of this application and must be converted in order to build in this version of the application. To convert the solution, open the solution in this version of the application.

I have googled around and haven't found any thing has worked. I know some of the common csproj aren't the issue but there are a couple that only exist in this solution so I am looking for a possible cause in those.

Funny is when I build the solution locally all is fine its only when out release team builds it that there is an issue.
