Yes you can
"Can I clean install Windows 8 using a Windows 8 Upgrade download or DVD?"
Yes, you absolutely can clean install Windows 8 using an upgrade-licensed copy of Windows 8 or Windows 8 Pro. This includes both the Windows 8 Pro Upgrade download from Microsoft and the Windows 8 upgrade discs you can buy online and from retail stores.
If you have, or are planning to purchase, the Windows 8 Pro Upgrade download from Microsoft, see How To Clean Install Windows 8 Pro Upgrade for a walkthrough on how to properly prepare that download so you can use it for a clean install.
If you have a Windows 8 upgrade version in DVD format that you purchased from a retail store or online, there's nothing to prepare as long as you have an optical drive. If you need that disc on a flash drive, see How To Install Windows 8 From a USB Device for help doing that. It's not as easy as copying the files to the flash drive so be sure to look at the tutorial before getting started.
Important: You can only install Windows 8 (clean install or upgrade install) using an upgrade license if you currently have a copy of Windows 8, Windows 7, Windows Vista, or Windows XP installed on the computer. True, the clean install process involves removing that operating system, but it still has to be there when the Windows 8 setup process begins. Upgrade licenses are less expensive than full licenses because you're getting a break as a previous Windows customer.
If you install windows 8 on currrent hardware than transfer it to the newer hardware it will not boot because it needs the current motherboard to be present so It wont work. Sorry about that writters block
