cable(s) to migrate between imacs?
I've ordered a 2017 iMac, and I'm hoping to use migration assistant to transfer files to it from my late 2009 iMac. The old machine has a bad graphics processor, making it impossible to boot up successfully, so I think I'll need to access it in target disk mode from the new machine. What cable(s) and/or adapters will I need? The 2009 machine has USB 2 and FireWire 800, while the 2017 has USB 3 and Thunderbolt 3. And I suppose they both have Ethernet. How can I get this to work?
iMac, iOS 11.4.1
