Migrate pizigate to usb dongle sonoff zigbee

Currently, I have HA Supervised on Dietpi (Linux Debian), all on a Raspberry Pi 3. The gateway is a PiZigate v1. I have Zigbee2mqtt installed.

The plan is to migrate to:

Raspberry Pi 3 B+, ​​Sonoff Zeegbee USB dongle, HA OS and keep Zigbee2mqtt.

1/ I was thinking of backing up HA, but since I’m going from Supervised to HA OS, I was wondering if it would work?

2/ How can I transfer the current data from the Pizigate to the Sonoff dongle without breaking everything? Because if the backup from Supervised to HA OS works, which I’m not sure it will, I don’t see how the Pizigate data will end up on the USB dongle?

Hello toto6976,

Pi3 has barely enough memory, and if you add more than a couple of add-ons you will start running into problems. Just saying you are in the middle of a swap, maybe update that at lease a little…
