I’m trying to migrate my Intel NUC based HA setup that runs Ubuntu server with docker and HA to a supported configuration based on HA Operating System. Since the hardware itself (the Intel NUC in my case) still runs fine, I purchased an extra SSD so I can migrate as soon as I found the right approach.
I already installed HA based on the Home Assistant Operating System on the new SSD. My goal is to migrate at least certain addons like VaultWarden and Unifi controller, but If I can migrate other configurations and addins without pain that is also appreciated (Plex, MySQL, Adguard etc.).
What is the right approach here? Create backups of the configurations I mention and copy over the backup files and restore them on the new installation? Or will this only work if I first setup my new configuration with the same addons and then restore?
