Help to migrate from Jeedom Atlas to Home Assistant

Hello thanks for your help

I only have a bluetooth and zigbee sensor for the moment.

Jeedom Atlas spec:

6-Core 64-bit Processor
Dual-core Arm Cortex-A72 64-bit @ 2.0GHz
combined with a quad-core Arm Cortex-A53 64-bit @ 1.5GHz
RAM: 4GB DDR4 RAM
4 external USB - 2 x USB.2 and 2 x USB.3
Emmc 32GB hard drive
ZigBee antenna
WiFi 2.4 and 5 Ghz integrated
Integrated Bluetooth 5.0
Integrated RTC battery
Power supply 9V 2A USB-C EU plug

I m actually looking to flash using this ubuntu image (rock 4A if I m correct) My modem tell me it a rockpi 4B :thinking: Rock4/downloads - Radxa Wiki

Maybe using this image of HA: GitHub - citruz/haos-rockpi: Home Assistant OS for Rock Pi 4
if possible on a docker

Full home using Philips Hue (+50 lamp and accessories) lamp with 2 bridge.
Ecowater system
Belgium electric communicating counter
Yale lock system (with bridge)
Ecovacs deebot
Gardena sileno automower
mercedes car
powerdale nexxtender charging solution (using iot)
Vaillant calormatic 350
Android TV Shield
Google home
AdGuard home on a pi3
Hormann garage door (bluetooth)

What want to do :
Collect data and store it in notion
integrat chat gpt
use MQTT

Futur stuff I want to buy/ integrate later
Ajax alarm system (only data collection)
Scrap ores, ecowater, antargaz data if I don’t find a plugin to do it.
automatic save backup on a cloud solution
nas

Best

Edit: It was a hell but I finally install ubuntu … I got a lot of issue (etcher crashing, several try to flash the rockPi, network issue ethernet, issue to get the ip from my modem)

I don’t know if I should let the usb card connected to the rockPi, tomorrow I ll trw to install HA but it look difficult, is there some command I can run to avoid using a usb card ?
