What

We are several versions behind on Proxmox on Coherence, as of writing the current version of Proxmox is 7.1-7 while we are still running 5.4-13(!). This means that we can't make any new LXC containers with newer distributions because they are simply not supported by Proxmox 5. Several attempts to upgrade Coherence have been made in the past, but I hope this time we can actually do it! It would also be nice if we could use this as an opportunity to clear old unused VMs and containers off Coherence.

Upgrade stuff (can be done already when backups are possible)

Please make backups first before you upgrade a VM or container

There should be a backup system available on backup-nfs before we start.

Debian containers should be Debian 10 at least before we can upgrade Proxmox, and Ubuntu 18.04 it seems.

Thinking steps required

• Backups - if we mess up, how do we bring things back?
• Redundancy - Can we upgrade some other host and migrate? Would this be a good plan going forwards?
• Upgrades - All VMs/Containers below need to be ticked off
