I had to do a clean install cause I moved from Win2000 ....
Damn that chart....damn it to hell. You should have seen the test matrix we had to go through to confirm that during Win7 beta. Multiply that times 11 different product lines (commercial desktops only; didn't even count consumer or mobile) and then multiply again for various hardware configs within those product families. I think if one of us had to do another upgrade test, we'd have jumped out of our 6th floor windows.
