How to move to a new version of Zigbee2MQTT that adds support for previously unsupported device that I used with an external converter?

I’m currently running a container based Zigbee2MQTT v1.35.1 installation integrated into Home Assistant. The release notes for v1.35.2 mention this: " #6917 Support sensor for TuYa ZWT198/ZWT100-BH (@vobelic)". I have an Avatto ZWT-BH-3A thermostat that wasn’t officially supported before, and I resorted to an external converter found in a GitHub issue. So right now my Zigbee2MQTT configuration file has the following lines to support my thermostat:

external_converters:
  - _TZE204_lzriup1j.js

I would like to update my Zigbee2MQTT installation to the new version, without renaming my existing thermostat and without losing its historical data, while removing this external converter, so that I use the new built-in support. What’s the best way to achieve that?

Zigbee2MQTT’s default name is created from the device IEEE-address. This does not change whether you use an external convertor or not.

Simply upgrade, and comment out the external convertor.

Thank you, i did just that, and no surprises.
