Q: Can I move the HDD and keep the data from ASUSTOR NAS to another ASUSTOR NAS？

2025-08-05

Yes。
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 disks 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 disks from one system to another without need for transferring data or re-installing the entire system.。

Steps:

Power off your NAS  -> move the HDD to a new ASUSTOR NAS  ->  Power on the new NAS.

 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.
