I have a MBP that has Logic on it as well as Apple content such as Jam Packs and my 3rd party plugs. Fortunately, all my 3rd party sample content is on an external drive, so that should be a matter of establishing new data paths. After a good deal of review of posts from Logic/Mac gurus here, I guess I'm going to do a fresh Snow L install and then just feed the new Mac Pro with all the DVD's of Logic and my Plugs like Ivory, then go get updates for everything. Tedious but professional I gather. One thing I'm wondering about is my own user stuff. I don't think I know enough about my computer's file structure to be able to hand pick and transfer everything of my own from projects to templates to plug settings. Can Migration Asst be of any help at some point in this way after I get everything running? I know it's going to be worth it having the 8 core Nehalem with 4 drives, but I'm fretting. I have a query in to Synthogy about how to do the RAID 0 for Ivory. Any tips on how to add one's personal files, I mean my projects and settings, templates, etc? Is there an old post or manual/help page explaining how to cherry pick the user material and transfer it? To be honest, I've never fully grokked on where all my stuff lives. New puter comes today. Thanks people. I've already learned a lot by studying here. It's always been worrisome to me to move to a new computer, but I'm preparing for a 64 bit world.
