Upgrading from Vista Home Premium to Windows 7 Professional?

I recently purchased the Microsoft Windows 7 Professional Upgrade. I am currently running Vista Home Premium SP2 (32 bit). I have used the Windows 7 Upgrade Advisor and the result was, in order to upgrade to another version of Windows I must perform a clean install of Windows 7 professional.
My question is: "Can I do a clean install of Windows 7 (upgrading from Vista Home Premium)using the Microsoft Windows 7 Professional Upgrade Version."

I have done some research about this issue No one (including Microsoft) has a definite answer on this subject.

My basic PC Stats: Windows Vista Home Premium
AMD Athlon 64x2 dual - core Processor TK57,3.0 GB RAM, ATI Radeon Xpress 1250

Any advice would be helpful. Thank you.

Existing OS must match intended install ...

In other words, to 'upgrade' to Windows 7 Professional - you MUST have already installed Windows Vista Business.

Windows Vista Premium can only be 'upgraded' to Windows 7 Premium.

I fear you are misinterpreting what the Windows 7 Upgrade Advisor is telling you.

*Microsoft will only allow the following upgrade paths to Vista users. For example, users who purchase an upgrade copy of Windows 7 Professional and have Vista Home Premium will only be able to perform a clean install. Here's the migration list:

* Windows Vista Home Premium to Windows 7 Home Premium
* Windows Vista Business to Windows 7 Professional
* Windows Vista Ultimate to Windows 7 Ultimate

If you are performing an upgrade installation from Windows Vista, the base language must match the target Windows 7 language, you must have about 9GB of free space for the installation, and the installation can only occur on the same partition that holds Windows Vista. Existing applications and user data will be automatically migrated to the new Windows 7 installation.

Clean installs will require about 16GB for the installation process. Unless the user chooses to repartition or format the current partition, Vista's files from C:\WINDOWS will be preserved under C:\WINDOWS.OLD, just as when upgrading from XP to Vista. Clean installs will also have to be performed when upgrading from a 32-bit version to a 64-bit version.

Yes the process is quite simple really. All you need do is Wipe the HDD in the computer

With something like Boot & Nuke

or Kill Disc

Then place the the Windows 7 Upgrade Disc into the DVD Drive and boot the system. The Upgrade version of 7 will then proceed to install and if it is anything like previous Upgrade Versions of Windows it will ask you to insert the Vista DVD into the Drive to confirm that you can Legally use the Upgrade Disc. After it has confirmed that you are using the product correctly it will instruct you to replace the Windows 7 Disc into the DVD Drive and complete the Install.

However you are likely to need to install any Drivers for your Hardware after you have finished the Windows install to get all of the hardware working. The most likely ones are the Sound Drivers, the Video Driver and any Network Drivers that may be required for your Hardware.

You'll also require the Original Recovery Disc for your system.
