Switch from Mac to Windows

I bought Rhino 5 for Mac (with upgrade to 6 for Mac when it comes out) a year ago but am now thinking about buying a Windows laptop. Does anyone know if I can switch the license over to Windows?
And/ or will it be possible to use the zoo cloud thing to share the rhino 6 license across Mac and Windows?
Thanks!

Your Rhino 6 license is “dual platform” meaning it can be used for Windows or Mac V6.
Install Rhino, start it, click Login, provide your Rhino login account credentials.
