I'm going to be getting the Haswell iMac and will need to transfer 1.7TB of stuff from my Mac Pro to the new machine. I'll want to use Migration Assistant to transfer the startup disc (about 300GB), and then just get access to my secondary storage drive and copy the roughly 1.4TB of stuff from there onto the iMac as well (I'll have the 3TB fusion drive). I was thinking of getting a Thunderbolt to FireWire adaptor. Is that the best option? I would need to get a FireWire 800 to 800 cable from OWC, and then the Thunderbolt to FireWire 800 adaptor from Apple. Is this the route you'd go with? Thanks!
