Prep for HA Yellow

Installation
1

I’m currently running a HA container on a Pi using docker, with 2x Yellow PoE kits on order. Provided I’m able to source some Pi CM4 boards (fat chance) could I install HA OS on the CM4 and run it on the IO board for the time being and then simply swap it into the yellow?

Additionally, what is the best why to backup my entire HA config and move it into a HA OS install?

Backups, on another computer.

There are two useful addons, one backs up to google drive, the other to a samba server.

I am wondering if it will be compatible with CM5.
Also, if i choose the PoE version, can I still uses the WiFi of the CM module? Sometimes I will need to move my HA Yellow and connect it to wifi.
