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.

1.1 System Migration

Older NAS devices may not receive the latest updates to ADM when support ends. This means that there may be a version mismatch. If using an older NAS as the target NAS for system migration, please ensure that the ADM version of the target NAS is equal to or greater than the ADM version on the source NAS.

Note:

• Volumes with a cache drive mounted cannot be migrated. SSD caching must be unmounted before performing system migration.
• The number of drive bays in the target NAS must be equal to or greater than the number of drive bays in the source 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.
• To migrate an M.2 SSD volume, the target NAS must have at least the same number of M.2 slots as the source NAS. The first M.2 slot of the target NAS must contain a M.2 SSD.
• To move your CloudID to a new NAS, please follow the steps below to modify the CloudID on the source NAS.
  • Select EZ-Connect under Settings on the source NAS.
  • Click Rename and give your NAS another cloud ID to release the original and click Apply.
  • Once you have migrated to your new NAS, use the same steps above to rename the CloudID to the CloudID you originally intended to use.

The ADM version of the target NAS is equal to or greater than the ADM version of the source NAS.

• Power off your NAS.
• Transfer all of the hard drives from your NAS to the new NAS and power it on.
• After rebooting, ADM will work properly.
• Please upgrade all apps on App Central if needed.

If the ADM version of the source NAS is above 4.1, do not attempt to migrate to these models of NAS devices: AS10, AS50, AS51, AS70, AS-20, AS-30 and AS-60.

If the ADM version of the source NAS is above 4.0, do not attempt to migrate to these models of NAS devices: AS-20, AS-30 and AS-60.

Product Support Status

1.2 Additional notes

• 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.
• The maximum single volume capacity of 32-bit NAS devices is 16TB. This means that the AS-20, AS-30 and AS10 series cannot create volumes with a total size larger than 16 TB. While volumes migrated from these models will work properly in newer NAS models, the capacity of the volume created on a 32-bit NAS will still be limited to 16 TB. To use the maximum possible volume size on a newer NAS device, ASUSTOR recommends to transfer all data to a separate storage device and rebuild the volume on the newer NAS.
• If the Volume capacity of the source NAS is greater than 16TB, do not attempt to migrate to these models of NAS devices: AS10, AS-20 and AS-30.

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