New homeserver - migrate from pi4 to proxmox / docker?

Just putting in a plug for Proxmox: it’s not just for professional users. I’m very much an amateur and knew nothing of Proxmox, but by following this excellent guide had no problems setting it (and HAOS) up on my old laptop. It’s been rock solid, and being able to make a clone of the entire HAOS environment prior to an upgrade or major change is fantastic.
