TTN V2 to The Things Stack V3 Transition

TTN V2 to V3 Upgrade
9

I posted some generic information here: The Things Network upgrade to V3

Let’s discuss the migration from V2 to V3 here.

I understand the potential coverage issue that may occur when migrating gateways now from V2 to V3.

What is highly advised is to migrate devices as soon as possible to V3. Gateway coverage is already there. We support all application level integrations as we do in V2, including storage API, MQTT and webhooks.

See Migrating from The Things Network Stack V2 | The Things Stack for LoRaWAN. When you migrate, you can convert your V2 devices to ABP devices, i.e. remove the AppKey, so the end device will not join on V2 anymore.

Then, if your device has a mechanism to detect link loss (missed acks, missed ADR acks, link check misses etc), it will revert to join mode and join automatically on V3.

So the order would be:

  1. Create applications now on V3 and adapt your application to the new payload formats etc. Few changes, but all minor
  2. Migrate devices now from V2 to V3 and convert them to ABP in V2: Migrating from The Things Network Stack V2 | The Things Stack for LoRaWAN
  3. Follow @htdvisser’s steps mentioned above
