Is it possible to upgrade from Windows 8.1 to 11 using old OEM Key?

I'm still running Windows 8.1 and thinking about buying a new SSD and do a clean install of Windows 11 on it. I have windows 8.1 OEM Product Key. Will this work for Windows 11 or I have to buy new one?

    Not possible. Microsoft no longer accepts Windows 8.1 keys for new Windows 11 activations.
