We had this issue when doing an in-place upgrade from Windows 7 to Windows 10 (1903) on certain machines while many others went through the process w/o any issue.
We couldn't install Windows 10
We've set your PC back to the way it was right before you started installing Windows 10.

The installation failed in the FIRST_BOOT phase with an error during MIGRATE_DATA operation

The affected machines would finish all the installation process but stopped when loading updates around 40% t0 65% and would reboot and revert to Windows 7.
Disabling AV, running sfc/scannow
, and check the installation file integrity didn't help.
