I wrote something on another post, here’s the link:
Initially, I used a modified snapshot to restore. I modified it by removing deconz addon as my RPi had a Raspbee shield plugged into the GPIO and for the NUC I had to use a Conbee. The Raspbee and Conbee both have the same chip. I had some issues, all down to me, very rookie mistake. I thought I was having problems with DNS as I could not remote using Duck DNS, but it turns out that I hadn’t changed my port forwarding, otherwise install was simple. So during a re-install, I installed the addons and then I copied over the configuration, automation, script, groups and lovelace-ui .yaml files. As fter I was done, I deleted the home-assistant_v2.db, so that there was no legacy info in the database. All running smoothly now.
