What happens to the Windows 7 key when upgrading to Windows 8?

I would like to upgrade my Windows 7 PC to Windows 8. I currently have an academic license key for Windows 7, which is basically a full license key, not an upgrade. After the upgrade, I would still like to have a Windows 7 partition that I would create after the Windows 8 install.

Since the Windows 8 key is an upgrade key and Windows 7 key is a full key, does it kind of "deactivate" the Windows 7 key since I upgraded the OS? Or the Windows 7 key is still usable on my machine and it would be possible to install it along with Windows 8?

Best Answer

No, Microsoft specifically mentions this in all its upgrade license terms. The previous version is replaced by the new upgraded vesion. You can't have it both ways - upgrade and keep old.
