We have created a BizTalk Solution in VS 2013 Premium version. Now we have upgraded the Visual Studio version to VS 2015 Enterprise version. But when opening in VS 2015 it says BizTalk Project is incompatible. I went through [this MSDN article](http://BizTalk%20server%20projects%20are%20not%20compatible%20with%20Visual%20Studio%202015%20or%20Visual%20Studio%202013.). But its says

We used BizTalk Server 2013 R2 for developing the BizTalk Solution. Do I need to reinstall BizTalk for solving this issue?
