I have only recently moved to proxmox as the Hyper-V licensing became too opressive for hobby/one-person projects use. Can someone tell me wether proxmox upgrades are usually smooth sailing, or should I prepare for this being an endeavour?

Never had a problem with them. Just put each node in maintenance, migrate the VMs to another node, update, move the VMs back. Repeat until all nodes are updated.

  if you are using hardware pass through for e.g. nvidia cards you have to update your VMs as well, but other than that pretty painless in my experience (over 15 years)

  The "update" step is a bit of a "draw the rest of the owl" in the case of major version updates like this 8.x -> 9.x release. It also depends how many features you're using in that cluster as to how complicated the owl is to draw. That said, I just made it out alright in my home lab without too much hullabaloo.

    Did you do the backup and full reinstall or just with apt? I should do the same update this weekend. .

      Just with editing the apt sources and running apt commands. There is a nice pre-conversion checker which will alert you to anything special you have to (or may want to) do prior to beginning that process.

Proxmox ships a tool that verify if everything is right for the update (eg: pve8to9), and the wiki documentation is extensive and kept up to date. At work we started with 6.x a few years ago, upgraded to 7.x a bit after releases, then same with 8.x without issue. We'll wait a reasonable while before upgrading to 9.x but I don't expect any issue. Note : same with integrated ceph update, did Reef to Squeed a few weeks ago, no issue.

Usually smooth. But if you're running a production workload definitely do your prep work. Working and tested backups, upgrade one node at a time and test, read release notes, wait for a week after major releases, etc. If you don't have a second node I highly recommend it, Proxmox can do ZFS replication for fast live migrations without shared storage.
