You can use Migration Assistant log files and status files to troubleshoot migration failures.

About this task

If the migration fails, Migration Assistant generates a log file bundle on your desktop.


  1. Navigate to your desktop folder and open the file, where time-of-migration-attempt displays the year, month, date, hour, minutes, and seconds of the migration attempt.
  2. Retrieve the log files from the .zip file on your desktop.
  3. Retrieve other log files and status files.
