I set up Migration Assistant to move data between my wife's old MacBook Pro (2010) to a new 15 inch Retina MBP. It's been 21 hours since I started the process, and the time estimate keeps getting bigger. It started by telling me it would take 31 hours, at some points it revised the estimate to 75 hours, and even went up to 108. This morning it is saying 49 hours...
I am using the FW800 to Thunderbolt adaptor that came with the MBP.
I've been through this process before with other Macs, and I never ever experienced such ridiculously long times. I don't think there is more than 200GB of data that I am moving.
Is this normal? Should I wait TWO MORE DAYS to be able to use this machine?
Should I cancel and start over? If I stop the process and start it again, will it "credit" the amount of hours and data it has already moved? Is there any chance relaunching the process will speed it up?
thanks for any help
If you're able to use a Time Machine backup of the old computer as a source for the migration, then do that. The Applications should be in there, as well.
All that you're describing about the old computer point to a failing hard drive, which will explain the behavior when migrating the data. Making any changes to its OS might only make it worse, since there's a chance the drive might fail completely in the process. When a HD begins to degrade, you need to avoid writing to it as much as possible, using it only to read data from it for backup purposes, if at all possible.
Also, for the transfer to "accidentally" go through WiFi, you need to "accidentally' select the network option in Migration Assistant, and "accidentally" enter the verification code on the old computer... Etc etc. My point being, not likely that the transfer is going through WiFi, or that that is what's causing the problem. My money is on a bad HD on the old computer.
