Planning on ordering a new 2011 iMac with a 256GB SSD and 2TB drive. Current 2010 iMac hard drive has one drive with about 375GB. In previous migrations - it was as simple as booting the source Mac with the "T" and allowing the transfer via Firewire. The full image will not fit on the 256GB SSD. I know I can manually move user files to an external drive and reduce the image for a full copy and then move that data to the HD on the new iMac. Any better suggestions?
