homelab

Hi, so I have a very individual homelab. It's a collection of stuff accumulated over nearly 30 years of doing weird stuff.

For the past 9 years it's been running as a bunch of lxc containers (privileged because unprivileged did not exist, back then) but several of those containers are p2v conversions of physical hosts dating back to debian woody and earlier. They're all upgraded to at least buster, most are bookworm. Stuff like asterisk, email, home assistant, nextcloud, matrix synapse run there these days.

The server is a 15 year old HP gen6 thing, and is getting quite long in the tooth. There's also a dedicated cheapy microserver with an i4 running opnsense on bare metal as a firewall.

Trying to run stuff like local voice stuff for home assistant is showing the HP's age quite badly. Also, our area is getting fibre, and the opnsense box is maxed out at gigabit. More speed would be nice.

So, I'm in two minds. The homelab has been a lot of fun over the years, but I'm over 50 now, I want lower maintenance. This latest wave of upgrades is making me rethink the next 20 years of homelab. I don't want to leave something stupidly "only me" if I were to die tomorrow (diabetes is a fickle bastard). My wife might want to try and carry on this thing - it runs some useful stuff around the house (but it should be noted that nothing in this house requires a server or cloud) - and that's not going to happen with the current solution.

I think I might have a path, using proxmox, from where I am now, to something that can be deployed on e.g. a bunch of ms01 class devices. I'm thinking to convert the existing HP server to proxmox, to allow me to redeploy all my existing lxc containers into the proxmox world. As I acquire hardware over the next year, I can look at a k8s migration of the services onto a small, MUCH lower power cluster. One of the keys is that I don't want to have big outages of services for days or weeks while I migrate everything so it's gotta be a rolling upgrade as it were.

I'm here soliciting feedback. Has anyone ever migrated from a deeply legacy homebrew homelab into something like this? Does it reduce the workload long term? What's the practicality of this for someone rather less tech savvy?

Thanks!
