Hi... I've got the Leopard upgrade disks for my iMac (24" C2Duo) and have been waiting for some free time to install the new system. Is it possible to: - automatically back up all my applications and data files; - erase my iMac and install Leopard; - reinstall the applications and data files *automatically* without reinstalling Tiger system files? ... or at least some variation of the above? I've heard it's better to go with an erase and install as opposed to archive/upgrade and install. Basically, I want to be lazy (!) and not reinstall every single application from scratch.
