Moving to new home assistant instance

Configuration
1

I know this has been asked many times in many different ways, but I want to ask one more time. Maybe its a slightly different question. :slight_smile:

So I have a current instance of HA running well, I’m moving to a newer lower power computer. Old MS surface pro 1st gen. I’ve already got ubuntu 18.10 installed, HA installed and the devices that were discovered set up and configured.

I have not “moved” to the new device yet, because I want it to be reasonably seemless. I think getting all of my components, etc will be easy. My question is mostly about zwave. I have 40ish zwave devices. My understanding is if I just unplug the zwave stick from my current HA install and plug it into my new HA install, it will all just work. All the devices will be there and I wont have to do anything. I suspect it will be pretty easy, but not sure it will be that easy. So I have two questions

  1. Is it really that easy, is there any sort of configuration I need to do afterwards, like renaming, etc?
  2. If I move it over and realize it’s not going as well as I’d hoped and plug it back into my current HA install will it be back to normal, or will it require a bit of work because it had been running on a different instance of HA.

Mostly just trying to avoid spending the weekend fixing my zwave network, remove/readd/rename, etc

Thanks

Bonus for zigbee info as well. I dont have nearly as many of those devices so if I had to remove and readd it would not be the end of the world

I’ve done this a few times.

As long as you have a good ozwaveconfig.xml file, just plop that in the new folder with HA off, plug in your stick and you are good to go. You’ll need to makes sure you also bring over your .storage files because you don’t want to rename things or deal with that.

What I end up doing is piece mealing the config. Bring pieces over at a time. You could just plop the whole thing over and it would work, but you’d need to update hardware settings and IP’s if they changed. It’s way easier than you expect.

Just wanted to report back on this. Moving over was a snap, just like everyone said. :slight_smile:
I’m now running ubuntu 18.10 on a old surface pro 1 (i5, 4gb, 128ssd), and it’s working like a champ. Super quiet, pretty low power requirments, battery backup, and super small. I have a usb gigabit adapter, which is also a 3 port USB hub. So my zwave/zigbee controller is plugged into that. I like this better than a NUC due to the size, and also because I already had one, haha.

I did like you and brought it over a bit at a time.
