I have recently bought a MacBook pro with iLife 08 pre-installed. However inn the box was 2 Mac Os X Install Disk 2 disks. Im guessing that install disk 1 is the disk which iLife 08 is on. I am buying Leopard next week. If I upgrade from tiger instead of doing a clean install, will it retain all of my files and programmes on the MacBook Pro and put them into leopard or will i have to install everything again and buy another copy of iLife 08 ? Forgive my ignorance, i've only been a Mac user for 2 months.
