As described in my earlier post I made some extensions to the Test Case Migration Tool, http://tcmimport.codeplex.com/ so it can handle importing old test cases in word documents to Microsoft Test Manager. Recently I have tested to import 100+ test cases with a slightly different template. Of course its always something that can be done better so I've updated my extensions to be more tolerant to differences in templates.
