When trying to migrate from TFS 2010 to Visual Studio Online we are getting the error "Template Customization or Template Mismatch error". We know there have been a few customizations like adding more choices to dropdowns but don't know which ones or if there are other changes. A few people here suggested applying an uncustomized template to the projects in TFS but it's not clear which templates should be applied.
We have a project that uses the CMMI template but there are three versions of this on the TFS server - 4.0, 4.2 and 5.0. I don't see any way to tell which one was used to create the project. As a matter of fact the only reason I know it's CMMI is it errored when I created a project in Visual Studio Online with the Agile template and tried to migrate to that.
To add to the confusion, VSO only has templates with version 2013.3 so the project I'm migrating to uses the CMMI 2013.3 template. Should I add the older templates to Visual Studio Online and create my project using the same template?
Which template should I apply to the project to make it able to migrate? Should it be one of these or should I use the 2013.3 template?
Lastly, how do I get a copy of the uncustomized templates? Do I need to create a new project and export it?
Thanks, Bill
