    I'm currently running Lion GM but want to do a clean install with the official lion release. Then I want to restore all my documents from my time machine backup.

    Will this work? What is the best way to go about this?

    search the forum on how to make a Lion DVD or USB boot disk. Boot up with that, format your hard drive, then install Lion.

    Actually, I just noticed the GM build is exactly the same as the app store final release. But its still a good idea to do a clean install if I'm having some problems here n there?

    This is how I updated to Lion:

    1. Backed up my data from Snow Leopard to an external firewire enclosure via Time Machine.
    2. Installed a fresh copy of Snow Leopard from the install disk that came with my mac.
    3. Downloaded a copy of Lion from the App Store.
    5. Install Lion.
    6. Restore my iTunes folder and Documents from my Time Machine backup.
    7. Enjoy. :)

    I had no errors or anything throughout the process.
