    Hey,

    I've just recently bought Lion from the App Store and installed it on my iMac. I also want to install it on my MBP, but my connection really sucks and it takes 10hours+ to download it. So I burnt the .dmg file using disk utility onto a DVD.

    If I use this to install Lion, will I have an 'Upgrade' option or will I have to overwrite SL?

    Thanks,
    Louis

    Not sure if this is a good way to go about it but I installed Lion, re-downloaded the entire application and copied to a USB stick. I used the stick to install the OS on another of my laptops and it seemed to work well.

    I upgraded my Macbook using a DVD I made from the downloaded file. It worked perfectly.

    So it just upgraded and all your files were still there?
    Or did it install a Fresh copy of Lion?

    It's an upgrade. Just go ahead boot of the disk and do a regular installation and once it asks you which drive to install Lion to, choose the drive with SL already installed. It's only a clean install if your format your hard drive using Disk Utility before hand.
