I'm trying to use migration assistant from a 3-yr-old MBP to a brand new retina one. It would be moving about 420GB of data. I can't find a fast way to do it, despite the fact that other posters have said there is a fast way (see steve-p's post in http://forums.macrumors.com/archive/index.php/t-1406331.html thread). Here's what I've tried: 1. Accidentally by wifi, time estimate >100hrs. Riiight. Canceled that. 2. Ethernet (using thunderbolt-to-ethernet adapter that came with the rMBP) directly from one machine to the other. They didn't seem to notice one another, so I suspected I needed to involve a hub/router. 3. Ethernet (same adapter) through Verizon FiOS wireless router (using ethernet ports on back). >30hrs and increasing as I let it work. Canceled that. 4. Did a Time Machine backup of the old machine to a CloudBox (connected by ethernet to same router; have backed up there before, just updated it) and tried to restore that backup to the new machine (now only about 300GB; some stuff is excluded, like virtual machine images). Again >1day and increasing as I let it work. Canceled that. These seem wrong to me, because others have posted that ethernet should be able to do that much data in 2hr (see steve-p's post linked to above). So my questions are these: - Am I screwing the ethernet transfer up or is it really that slow, given what I have? (My router says 100/10 on it...does that mean it's not gigabit ethernet, so I can't expect a 2hr transfer time? My ethernet cables are old...does that matter?) - Is it possible to do a direct connection of one computer to the other by ethernet, but I just didn't do it right? If so, would that help with the transfer rate or not? - Would buying a thunderbolt-to-firewire adapter get me the transfer rate I need (to do it overnight)? If not, my best plan is to just do it over a weekend when I can wait days, I guess. Thanks in advance for any tips!
