As with any such system, you need a spare box. Upgrade the spare, move the clients to it, upgrade the original.

But then the clients have downtime while they’re being moved.

  • I don't know about Incus, but on ProxMox the downtime when moving a VM is around 200 ms.

  • Isn't that the exact problem that k8s workloads solve by scaling onto new nodes first etc? No downtime required.
