Is there any way to upgrade Windows Vista Home Premium to Windows 7 Professional?

Is there any way to upgrade Windows Vista Home Premium to Windows 7 Professional? It's not supported in the official upgrade matrix, but is there some way to change a config file and make this happen anyway? I know it can be upgraded to Ultimate so Professional would seem to be a business choice rather than a technical one. Is there a way around this?

"One possible way to do this would be to upgrade to Windows 7 Home Premium as a demo and then upgrade to Windows 7 Professional. You could then put in your key. I will test this in VM and get back to you with confirmation.

You have to create an All-In-One version of the Windows 7 install DVD to do this. Instuctions can be found here:

UPDATE: I am wrong! :( If you try to do what I recommend, you get this message:

To upgrade from one edition of Windows
7 to another edition of Windows 7, use
Windows Anytime Upgrade. Cancel the
upgrade, open the Start menu, and
search for Windows Anytime Upgrade.

I haven't been able to find a way around it."

"You can't upgrade your computer running Windows Vista Home Premium to Windows 7 Pro, what you'll need to is a custom or clean install from upgrade media. This option doesn't preserve your programs, files or settings. It's sometimes called a ""clean"" installation for that reason.

The Windows Easy Transfer tool creates a single file containing your files and settings for back up to external media and subsequent restore on the fresh OS.

This is the MS custom installation guide for a Vista to '7' custom install."
