I work on trying to script each install. So if I need to repave, I have a documented, working script, and the source bits to work with. I've preferred VMs for functional appliances for a while now. I like the isolation compared to containers. Though YMMV. Right now, the hardest migration I have is my mail system, which makes use of a fairly powerful pipeline of filters in various postfix connected services. Its not fragile, but it is hard to debug. I host it myself, as the core thesis of the article pointed out, you can be deplatformed, for any reason, with no recourse. And if you lose your mail, you are probably in a world of hurt. The one thing I am concerned about is long term backup. I need a cold storage capability of a few 10s of TB, that won't blow up my costs too badly. Likely the best route will be a pair of servers at different DCs, running minio or similar behind a VPN that I can rsync to every now and then. Or same servers with zfs and zfs send/recv. Thinking about this, but still not sure what to do.
