Best practices to upgrade a VM Scale Set between OS versions?
If I have a Scale Set with a set of stateful VMs using local OS disk for data, what would be the best practices to upgrade the OS from eg Ubuntu 20 to Ubuntu 22? Is it possible to do it without data loss? Auto upgrade only supports minor versions.
