I'm evaluating SourceGear vault, so I hope this is a valid question

We have a variety of Visual C++ 6.0, Visual Basic 6.0, and Visual Studio.NET 2003 projects already under VSS.
Now, last week we evaluated SubVersion, and one of the things we needed to do after the migration was complete was to open up the .sln files in notepad, remove all references to VSS, then open up VS.NET, and add the project to SubVersion manually through the plugin.
Will I have to do the same thing with Vault? Is there a conversion tool that can remove all VSS references, or will the Vault "ignore" VSS references and replace them accordingly?
Thanks for your help,
Julian
