Step by step

   Perform a final Time Machine backup

   Ensure all data is migrated to your new device. Connect an external storage drive and run a full Time Machine backup to guarantee no critical files are lost before the drive is formatted.

   Note: Do not skip this step; once the drive is erased, data recovery is impossible.
