Migrate from HA Container to HAOS

Hi,

I have a Rock64 running Ubuntu with HA running as a Docker container. And I want to migrate to a HAOS installed on a much more powerfull and up-to-date Proxmox server (in the same network, but different IP).

But how do I migrate without the need to start a fresh config on the new HAOS? Can I just make a backup on HA Docker, and restore this in HAOS? Do I need to use the same IP? Do I need to turn off the old HA container before booting the new HAOS?

Yes

No

Would make sense while not strictly technical necessary.

Actually booting the new HAOS to the on-boarding screen obviously is no problem. You can then (instead of creating a fresh config) upload your backup. When doing this might be a good time to shut down the HA which the backup comes from. It very much depends on the services/integration/devices you are using if they are capable being connected to more than one HA instance at a time (esphome for example has no problems with this) :bulb:
