I will be getting a new Mac soon and I'd like to know a few things about setting it up. First, should I just use the migration assistant to straight up copy my current machine to the next? Are there any possible performance issues that could arise from basically cloning a late 2009 iMac to a new Mac Pro? Or is it better to start fresh, and just re-install apps, xfer over data files and re-link them? For example, this would be a sizable Lightroom Library. I have Adobe Creative Cloud so getting started there would be as simple as downloading the apps to my new machine. 2nd question: I have an OWC FW800 raid 5 storing my photos, videos. I plan to move to a Thunderbolt or USB3 OWC raid 1 with the new machine. I have about 2.5tb of data on my FW raid. What's the best way to move THAT over considering the new machine will have no FW port? Airdrop?
