I wil get a new MBP next week. Unfortunately, I can't migrate from my old MBP to a new one directly but only from my backup on other disc, which doesn't have FireWire. Apple instructions are: You can connect your Macs in one of four ways to transfer information with Migration Assistant: - FireWire or ThunderBolt - Wireless (Wi-Fi) or Ethernet There is nothing about USB2 . My migration should be from Snow Leopard 10.6.8 to OS X Lion. Should I be worry how to do it? Any suggestions? Thank you.
