Update Raspberry Pi 4 to ChirpStack to V4?

Issue: RAK Wireless RAK2287 includes ChirpStack V3, a version behind (V4 available from ChirpStack)

Setup: RAK2287 with hat on Raspberry Pi 4 model B


Details: What is the best steps to upgrade the ChirpStack V3 that is installed following the QuickStart instructions? Specifically, how to install ChirpStack V4 without loosing all the connected devices and other settings?

Welcome back @jmeck

Did you check the ChirpStack v3 to v4 migration guide?

I followed it and it worked. All devices were taken over. Manual steps I had to do was to change the Gateway-Bridge MQTT format. It is somewhere hidden in the Chirpstack documentation what needs to be done.

For me, I had to add the region to the MQTT message format to get it working.

  event_topic_template="gateway/{{ .GatewayID }}/event/{{ .EventType }}"


  event_topic_template="as923_3/gateway/{{ .GatewayID }}/event/{{ .EventType }}"

@beegee thanks for the prompt reply! I missed finding the migration guide in my searching but will now attempt to follow those instructions. Thanks!
