Hello, I've searched these great forums regarding this, but I was hoping for some more advice. 1. I'd like to do an erase and install. Is this really better than a simple upgrade? If so, how can I get all my stuff back? I realize this is a silly question, but how can I get all my 17,000 iphoto pictures/folders/albums/slideshows, etc. back the exact same way they are now? (I have iphoto '06-but I will upgrade to iPhoto 09- will this be a problem when restoring my iphoto library?) Same with itunes? As I am new to this, can you give me a step by step process please? 2. I have several imovieHD/imovie'06 videos. How can I move my iMovieHD application over to snow leopard? Will it co-exist with iMovie09 when I upgrade to ilife 09? Note- I have the original discs that came with the computer 3 years ago In preparation for the upgrade, I did recently get SuperDuper and I've backed up my HD. Any advice how to proceed from here (for a "relative newbie") would be greatly appreciated. Thanks much!
