i'm going to buy an internal hard drive and the snow leopard box set (with ilife and iwork) likely in the next week or so, and i'm wondering how i should go about the upgrade to snow leopard. my current internal hard drive is dying, and i'm running on a boot-able external drive that was cloned from the internal just before the internal hard drive went bad. the external also serves as my backup. the hard drive is running 10.4.11 (don't have leopard), so time machine is out. 1. clean install, then migrate in this option, i would do a clean install of snow leopard on the internal hard drive, then migrate the info from the external drive to the internal to make it feel like a new drive. pros: feels like a new hard drive cons: will have to spend time trying to get back up to speed 2. clone, then upgrade in this option, i would use superduper! to clone the external hard drive to the internal hard drive, then do an upgrade to snow leopard on the internal afterwards. pros: can get back to normal after installing cons: upgrading from tiger, could have issues which option should i go with and why? thanks.
