Upgrade Vista Business to Windows 7

I purchased a Pavillion Laptop dv9000 from HP with Windows Vista Business 32 bit.  I also purchased a Windows 7 Home Premium Upgrade (32 bit) from Microsoft, intending to use it on my desktop computer, but I bought a new desktop with windows 7 instead.  I want to upgrade the Windows Vista Business on my Laptop but the Windows 7 Home Premium upgrade will not work with Vista business; i.e., I need Windows 7 Professional or Ultimate upgrade.  Already having an unused Windows 7 Home Premium Upgrade, what is the most economical way for me to upgrade my laptop to windows 7?

Upgrade paths:

When making significant changes to your computer such as an upgrade, it is always recommended you backup your system prior to installing a new version of Windows. In your case, you can upgrade to Windows 7 depending on edition and architecture of Windows Vista you have installed. If you are running a 32 bit version of Vista and want to upgrade to a 64 bit version (edition of Windows 7), you will have to a do clean install, this applies vice-versa.

If you are running consumer editions of Windows Vista such as Home Basic or Premium, you can only upgrade to either Windows 7 Home Premium or Ultimate. Also, you cannot do downgrades, which means, if you are running Windows Vista Ultimate now, you cannot downgrade to Windows 7 Home Premium. You must do logical upgrades:

Windows Vista Home Basic > Windows 7 Home Basic, Premium or Ultimate

Windows Vista Home Premium > Windows 7 Home Premium or Ultimate

Windows Vista Business > Windows 7 Professional, Enterprise or Ultimate

Windows Vista Enterprise > Windows 7 Enterprise

Windows Vista Ultimate > Windows 7 Ultimate.

In your case, the only recommendation, is to back up your personal files and settings using Windows Easy Transfer do a clean install.
