As stated in the title I'm moving to a new house soon(tm) that will change my home assistant instance a lot.
I was wondering what would be better... Start from scratch or adapt what I have? I have some information in HA that I want to preserve but most of it could go away.
Have you any experiences in this situation? Any insights?
I think it depends on how happy you are with the current setup. I have a bunch of old half finished junk for testing and no longer used entities so I would definitely start from scratch, but your situation may differ. At the very least I'd back up everything and export (including copying the Lovelace/dashboard yaml to a text file) it before starting over.
Same thing is happening to me. I even have some old stuff from Android devices that no longer exist and your comment just reminded me about it. I think I might start from scratch saving what I think is worth.
