clone APFS drive
hdiutil create -srcdevice /dev/diskXsY -format ULFO /Volumes/ExternalDriveName/YourImageName.dmg
In the above, diskXsY is obtained from diskutil list when you find the APFS container disk or HFS disk identifier.
Then, use:
asr imagescan --source /Volumes/ExternalDriveName/YourImageName.dmg
After that runs, you can then connect the external drive to the new MBP, use its internet recovery and terminal and do:
asr restore --source /Volumes/ExternalDriveName/YourImageName.dmg --target /dev/diskAsB --erase
Again, in the above, diskAsB is the MBP's disk identifier for its APFS container.
