SmartThings Hub v2/v3: Hub Migration Failed Error -... | digitalhomefaults.org

Technical Background:

The SmartThings hub migration process involves transferring device associations, routines, and custom SmartApps from the old hub (v2) to the new hub (v3) via the SmartThings cloud. This process relies on a stable internet connection, correct account authentication, and compatible firmware versions on both hubs. Issues can arise from DHCP lease expirations, DNS resolution failures affecting cloud API access, or protocol incompatibilities (Zigbee/Z-Wave) during the device transfer. Furthermore, reliance on cloud services introduces latency and potential single points of failure.

Symptoms:

Migration process halts mid-transfer with a generic “Hub migration failed” error displayed in the SmartThings app. The v2 hub might exhibit a flashing blue LED (indicating cloud disconnect), while the v3 hub remains in setup mode (blinking green LED). Error logs within the SmartThings IDE (if accessible) may indicate a timeout error or authentication failure.

Possible Causes:

Intermittent internet connectivity issues with the Bell Home Hub or Rogers Ignite gateway.
DHCP lease expiration on either the v2 or v3 hub, preventing cloud connectivity.
Firmware mismatch between the SmartThings app, v2 hub, and v3 hub.
DNS resolution failure preventing access to the SmartThings cloud services (AWS).
Zigbee or Z-Wave device pairing conflicts during the migration process.
Temporary outage of SmartThings cloud services in the Canadian region (AWS Canada).

Solution:

1

Verify internet connectivity on your Bell Home Hub/Rogers Ignite. Perform a speed test to ensure adequate bandwidth (minimum 5 Mbps upload/download).
2

Check the DHCP lease time on your Bell Home Hub/Rogers Ignite and extend the lease if necessary. Consider assigning static IP addresses to both hubs.
3

Ensure both the SmartThings app and the hub firmware are up to date. Force-close and reopen the app. Initiate a hub firmware update if available.
4

Power cycle both the v2 and v3 hubs. Unplug them from the power outlet for 60 seconds, then plug them back in.
5

Reset the v3 hub to factory settings by holding the reset button on the back for 15 seconds. This will erase any previous configuration.
6

If migrating Zigbee or Z-Wave devices, exclude them from the v2 hub before starting the migration process. This prevents device ID conflicts.
7

Contact SmartThings support (Samsung Canada) to report the migration failure and request assistance. Provide the hub serial numbers and relevant error logs.

Safety Warning:

Never attempt to disassemble or repair the SmartThings hub yourself. This will void the warranty and may pose a safety hazard. Ensure that your SmartThings account is secured with a strong password and two-factor authentication to prevent unauthorized access. Secure the hub physically to prevent tampering.

Prevention:

- Regularly check the SmartThings app for firmware updates and install them promptly. - Monitor your internet connection stability using online tools or your ISP's app (e.g., Bell MyBell, Rogers MyRogers). - Schedule a monthly power cycle of your SmartThings hub to clear temporary errors. - Before major SmartThings platform updates, back up your device configurations and routines (if available). - Periodically check the battery health of Zigbee and Z-Wave devices, especially before the Canadian winter, which can significantly reduce battery life.

Expert Tip:

Before initiating the migration, try a "soft reset" on the v2 hub by quickly pressing and releasing the reset button. This clears the hub's cache and can resolve minor connectivity issues. Also, within the Rogers Ignite app, temporarily disable the "Advanced Security" features during the migration process, as this may interfere with the cloud connection.

Frequently Asked Questions

•How do I check the firmware version on my SmartThings Hub?

Open the SmartThings app, navigate to Devices, select your Hub, and look for the Firmware Version information in the Hub details.

•What is the default DHCP lease time on Bell Home Hub and how do I change it?

The default DHCP lease time on Bell Home Hub is 24 hours. You can adjust it in the Home Hub manager by logging in via a web browser and navigating to Settings > LAN > DHCP Server. Rogers Ignite settings are similar but accessible via the Rogers app or web portal.

•My Zigbee devices aren't migrating. What should I do?

Before migration, exclude the Zigbee devices from the old hub. After the new hub is online, perform a factory reset on each Zigbee device and re-pair them with the new hub. Refer to each Zigbee device's manual for reset instructions.
