VSS migration to TFS - folder structure change caused project mismappings

A company did a VSS6 to TFS2010 migration, but the folder structure was changed during the migration (I don't think any tools were used). Due to the folder structure change, the relative project paths in solution files are invalid so none of the 50+ applications work !

My task is to fix it up. I'm looking for advice to help me scan through the solution files in VSS getting absolute project paths and then doing the same in TFS in order to re-ma all the projects to match the new folder structure in TFS.

I cant redo the migration either as development has continued by developers in a foreign country (they've taken开发者_JAVA百科 PROD DLLs to get the solutions working with invalid projects ref's).

I've done research but cant find any tools and dont really want to have to write a utility to do it, eg http://msdn.microsoft.com/en-us/library/envdte.projectitem.aspx
