MIgration Assistant from HFS+ (case sensitive) to APFS (case sensitive) I have a new 2018 MacBook Pro, OS X Mojave 10.14.2, hard drive formatted as AFPS (Case-sensitive) and an old 2009 MacBook Pro, OS X Yosemite, hard drive formatted as HFS+ (Case-sensitive, Journaled).  I believe OS X on the old laptop cannot be upgraded any further.

I am attempting to use Migration Assistant to move the files over from the one user on the old laptop to the new one.  When I get to the "Transfer Information to This Mac" step of OS X install on the new laptop, I fire up Migration Assistant on the old, and see it appear on the new as a transfer source, but with a yellow caution icon.  Selecting that icon displays a pop-up with the message:

**The selected source cannot be used for migration.**
This source is not using a Case Sensitive filesystem, while your Mac is.


I have confirmed in Disk Utility and About This Mac that both hard disks are formatted case-sensitive.  There is a big difference in that the old drive is formatted HFS+, and the new AFPS.

Initially, I was able to use migration assistant to transfer the files, up until I discovered that the new drive was not formatted case-sensitive, which of course caused problems with filenames that differ only by case.  So I used command-r to boot the new system into recovery mode, formatted that drive as AFPS case-sensitive, and reinstalled OS X Mojave, only to run into this issue.

So, how do I get the user and all their files from the old laptop to the new?
I was able to restore from a time machine backup.  Just had to manually do a up-to-date backup on the old laptop.

Still don't know why I was unable to do a system-to-system (both with case-sensitive volumes) migration.
