I manage a self-hosted version at work for the development environment but we use the paid, cloud version for production environments. Managing the self-hosted version is farily trivial (the catch is that, anyway, we don't provide SLAs or HA for the dev environment. My main advice would be to: 1. use ZFS, keep the docker-compose files along with the data volumes on a dedicated dataset 2. take a snapshot before every update, delete the snapshot when users confirm everything is working okay 3. for the love of god make sure you perform every minor version. I did have to do a 9.1.2 -> 21.5.x upgrade and it's been quite a PITA. In Sentry's defense, it was quite a jump. And in Sentry's honor, I was able to retain projects, users and most useful things (except events, but for the development environment who cares?). Upgrading to, say 21.5 to 21.6 was quite a breeze instead.
