I have been running HAOS on Raspberry for some years and I am now wanting to move to Proxmox VM. I have many automations and integrations that would be a pain to recreate/duplicate. Is it possible to migrate directly ? I backup to the Nabu Casa and tried a restore on the proxmox VM with various component options, all fail. Am I trying to do something that is not supported ?
Do a full backup of the old one. build the new one, turn off the old one, restore onto the new one.
When it all up and you are happy, then you can consider deleting the old one. But make sure it stays offlike when the new one it loading and running.
