Other cases where a clean install is necessary:

  • Going from x86 to x64 or the other way around.
Its my understanding that Windows 7 Ultimate is so different from Vista Ultimate that a clean install is necessary. I attempted to do an upgrade from Vista Ultimate to 7 Ultimate and it forced me to do a clean install with my files being placed in a directory named windows.old. I tried it so often I had a windows.old.004! That was a nightmare! Good luck.

I have upgraded vista ultimate to windows 7 ultimate on several occasions, and it is a supported upgrade path.

What about Home Premium to Windows 7 Ultimate. Should I just get Professional instead.

I need to ensure I get Windows XP Virtualisation

According to this you can't do an in-place upgrade to professional. You can check with the upgrade advisor maybe it will tell you what version you can upgrade to. Only Professional and Ultimate have XP mode, there is a feature comparison located here.

Looks as if I can do a Home Premium to Ultimate Upgrade, but not to professional.

You can upgrade to Professional but it will require a clean install.
