Correct. The "in-place" upgrade, which leaves your programs and files in place can only be performed for the following combinations:
Windows Vista Home Premium -> Windows 7 Home Premium
Windows Vista Business -> Windows 7 Professional
Windows Vista Ultimate -> Windows 7 Ultimate
This is taken from MS's Win 7 Upgrade site:
If you are not going in this order (for example, I am going from Vista Ultimate to Win7 HP), then you have to do a clean install. It will place your old install in a Windows.Old folder and install Windows 7 fresh.
But from what i understand once you perform the upgrade your previous versions of Vista key becomes deactivate and you cannot use the key anymore...so that means you cannot use it and if you have to reinstall, how would you do it? since you cannot install vista and activate it, let alone the inconvenience of doing that and time consumption
at this point i will wait until around end of September if they have not changed it will cancel and then wait a while and order an OEM full install of windows 7 when I get a new machine, this way too much of a pain in the ass
