Why don't you have backups? It would make everything so much easier.


Migration Assistant should not delete files from the source location as it only copies files. Now if you manually move files, then an interruption can destroy the copies on both source & destination.


You can try using a data recovery app such as Data Rescue. You will need to boot from an external macOS drive or put the Mac into Target Disk Mode so that you can connect the Mac with the data to another Mac. If you boot from the drive you are trying to recover data from, then you will overwrite the data you are trying to recover. You can also contact a professional data recovery service such as Drive Savers or Ontrack.
