How to use the migration feature to transfer data and configurations to the new NAS

Note: When replacing or upgrading a Buffalo NAS device, please use the Buffalo migration feature to transfer data and configurations. Buffalo NAS does not support HDD migration, manually take out the HDDs from the source NAS and insert them into the destination NAS is not supported.

The migration feature allows you to migrate data and settings from one NAS device to another on the same network. By using this feature you can replace a NAS device with a new device while saving time and effort. This KB will explain the migration from Buffalo TeraStation 3000/5000 series to Buffalo TeraStation 3020/5020 series.

For the details about Device Model Pairs for Data Migration, Transferable Settings, Feature Restrictions and Troubleshooting during Migration, please refer to the Buffalo NAS Migration Guide.

 

1.    From a migration destination NAS device WEBUI, navigate to the Management tab. 
Then click the “Migration” settings icon to the right.

2.    Read the displayed message about Remote Management Service displaying the migration target folders carefully and click OK.

3.    Since we are migrating from a TS3000/5000 series, select “Linux-based TeraStation” and click Next.
 
The migration wizard will start scanning the available migration source NAS on your network.

4.    Select a migration source NAS device from the detected device list, enter the admin username and password for the selected NAS, then click Next.

Note: If the migration target TeraStation is a TS5020/3030 with firmware version v3.00 or later but the migration source TeraStation is not, enable this TLS option on the target TeraStation from Management > Security/Encryption Settings to allow the communication.

 

5.    All shared folders on the source NAS device will appear on the list. Select folders to migrate and select their location on the destination NAS Drive/Array, then click Next.

6.    This step will show the calculated data size and the estimated time required to migrate. Click Next.

7.    It is recommended to select the target NAS folder to save a migration log.
If you set the option to “Exclude from migration target”, “trashbox” folders in the shared folders will not be migrated.

 
If you enable “Specify Suspend Time” from the migration options, you can have the migration process automatically suspend at the specified day of the week and time, such as during business hours.

8.    After completed the configuration, click OK.  Before the configuring process finishes, do not operate the migration destination NAS.
 
After finish, click OK.

Note:
While the migration process is running, the I73 message will appear on the WEBUI dashboard and NAS Navigator2, or on the LCD panel. When the process is finished, the I74 message will be displayed.

9.    Data and settings migration progress can be viewed from the migration settings menu. You can confirm which settings have been successfully migrated by referring to the settings migration log.

10.    (Optional) Network and power management settings can be migrated separately using the buttons on the lower left of the migration settings menu. 
     Click the “Migrate Power Management Settings”, then click OK.

11.    You will only be able to migrate network settings after all the data migration are finished. Click the “Migrate Network Settings” button.
Note: If you migrate the network settings before migrating the power management settings, you will no longer be able to migrate the power management settings after that.
 
Click Yes to start migrating.
 
When the following message appears, disconnect the Ethernet cable from the migration source NAS and click OK.
 
After complete, the network settings will be migrated to the target NAS. Use the migrated IP address to access the target NAS. Migration complete.
