In the documentation for 'How to move your content to a new Mac', we see:
If both computers are using macOS Sierra or later, just make sure that they're near each other and have Wi-Fi turned on. If either is using OS X El Capitan or earlier, connect them to the same network using Wi-Fi or Ethernet.
I presume it's implicit that if both computers are using macOS Sierra or later, they'll connect directly to each other (without requiring a separate wifi network)? Is this correct?
The reason I ask is because I currently have access to only slow wifi networks, which would pose a problem with the amount of data needing transfer.
