I'm about to install a seagate momentus xt drive but I need some help. Should I clone first and then upgrade the OS or upgrade the OS then clone? I'm running an early 2008 black macbook on OS 10.6.8. I've been using the original 320 GB but since thats getting full, I'm running low on space and I'm about to install the Seagate Momentus XT 750 HDD/SSD. I was wondering if it would be better if I cloned everything to the new drive first and then upgrade the OS once I dropped in the new drive into my laptop... OR ...Should I take the new and blank harddrive and install the new OS on it, then copy stuff onto it? OR should I ...do something I haven't mentioned? What would you all do and which process do you recommend?
