Applicable Products

  • All QNAP NAS models
  • TR-002, TR-004 external RAID enclosures

Overview

You can migrate data between two QNAP NAS devices using one of the following common methods:

  1. Copy data directly over the local network.
  2. Transfer data using a TR-002 / TR-004 DAS as an external USB enclosure.

Each method has specific requirements and limitations, which are described below.


Procedure

Method 1: Copy data over the network

  1. Connect both NAS devices (e.g., TS-119PII and TS-453E) to the same network.
  2. On the destination NAS, open File Station and use the Remote Mount feature (i.e. HybridMount app) to mount shared folders from the source NAS via SMB.
  3. Copy the files and folders to the destination NAS.

This method is straightforward and requires no extra hardware, but transfer speed depends on your network performance.


Method 2: Use the TR-002 / TR-004 as an external USB enclosure

Step 1: Prepare and configure the TR-002 / TR-004 RAID enclosure
  • Install disks into the TR-002 / TR-004 and set the mode switch (DIP switch at the rear) to RAID 1 mode. See the External RAID enclosure user guide for details.
  • Connect the TR-002 / TR-004 to a Windows PC and format the disks as NTFS.
  • Warning: Do not change the mode switch while the enclosure is connected to a NAS. Doing so can cause errors or data loss.
Step 2: Connect the TR-002 / TR-004 to the source NAS and copy data
  • Connect the TR-002 / TR-004 to the source NAS via USB.
  • Configure the TR-002 / TR-004 as an external storage device on the NAS.
  • Copy your data to the TR-002 / TR-004.
  • Once copying is complete, safely eject the TR-002 / TR-004.
Step 3: Connect the TR-002 / TR-004 to the destination NAS and restore data
  • Connect the TR-002 / TR-004 to the destination NAS via USB.
  • Configure it as an external storage device.
  • Copy the data to the destination NAS.

Important notes:

  • Changing the TR-002 / TR-004 mode switch while it is connected may cause data loss.
  • All data on the disks will be deleted when creating a new RAID group. Always back up important data before proceeding.
