Moving to new house. Start from scratch or reuse? - sh.itjust.works

Hello! As stated in the title I’m moving to a new house soon™ 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? Thank for reading!
