I just created a new Homeassistant-OS VM on my new homeserver, took a backup of my old #HomeAssistant install (running in Docker on a Raspi), uploaded that to the new one's "start from a backup" dialog and was back up and running 15 minutes later. And most of that I spent waiting for the upload, the restore, and the reboot after

That was impressively smooth - only a single thing broke (MQTT tried to connect to a broker on localhost, which I changed back to the RasPi's IP. Took me no more than a minute)

There's a couple of other services I wanna migrate, but they'll follow when I have a couple of minutes
