Changing License Key of existing VS installation

I have a fully configured installation of VS2005 professional on my development machine. It was licensed through a previous employment contract which has completed. I've purchased VSpro with MSDN Premium and want to convert this Visual Studio installation to my new VSPro/MSDN premium subscription without reinstalling. Ireally don't want to reload/reconfigure all the SW, patches and addons all over given all the work that went into getting it just the way I like it.

Is there some way to just change the license key that is authorizing it so that it will reflect my current license?

Thanks!
