OUTLINE





1. System Migration

1.1 System Migration

ASUSTOR's built-in system migration mechanism allows you to quickly upgrade from your current NAS model to a newer one by moving your original hard drives to a new NAS system. This function is also extremely useful in the unfortunate event of a system malfunction or failure. You only need to move your hard drives from one system to another without need for transferring data or re-installing the entire system.


Upgrading your NAS

If you are upgrading to a new NAS model, please follow the migration instructions outlined below.

  1. Power off your NAS.
  2. Transfer all of the hard drives from your NAS to the new NAS and power it on.
  3. After rebooting, ADM will work properly.
  4. Please upgrade ADM to the latest version if needed and update the corresponding Apps on the App Central.

If you wish to add new drives to increase the storage capacity of your NAS please see: NAS 352: Online RAID Level Migration and Capacity Expansion (adding new drives).




In the event of system failure

If your system has failed and you need to migrate to a different NAS model, please follow the instructions outlined below.

  1. Power off your NAS.
  2. Transfer all of the hard drives from your NAS to the new NAS and power it on.
  3. After rebooting, ADM will work properly.
  4. Please upgrade ADM to the latest version if needed and update the corresponding Apps on the App Central.




1.2 Additional notes

  • The number of drive bays in the destination NAS must be equal to or greater than the number of drive bays in the original NAS.
  • When migrating to a new NAS, the first drive bay of the new NAS (counting from the left hand side) must contain a hard drive. The order in which the hard drives sit in the drive bays does not matter and does not have to be the same as in the original system.
  • If you are using EZ-Connect, you must re-enable it after system migration.
  • In order to prevent accidental data loss, we strongly recommend that you first back up the data on your NAS before migrating your system.
  • The btrfs hard drives cannot migrate to the AS10, AS-20, AS-30, AS-60, AS11, AS33 series.
