How to re-prompt conversion of vcxproj files from version 11 (VS2012) .sln file to version 12 (VS2013)

Hi,

I went to convert my sln from Visual Studio 2012 to Visual Studio 2013. I opened the solution in VS2013 and before being prompted with the option to automatically convert my vcxproj files for me it reminded me that I had code changes not yet checked in. So I closed out of Visual studio 2013, opened the solution in 2012 then checked in the changes. When I went back and reopened the solution in VS2013, I was no longer prompted to convert the vcxproj files, though I was now ready to. What do I need to do to be re-prompted?

Thanks for your help,
