etcd upgrade patch level

[Alex Epifanov]

Hello team.

I have a question about patch level upgrade etcd. For example from 3.5.7 to 3.5.16.

I have read docs https://etcd.io/docs/v3.5/upgrades/upgrade_3_5/ and found information only about minor upgrade from 3.4 to 3.5 but nothing about patch level.

My configuration consists of 3 nodes with auth enabled. Could you please explain how to upgrade from 3.5.7 to 3.5.16 with zero downtime cluster.

[Alex Epifanov]

Thanks for your explanation.

Hi Alex,

There should not be any breaking changes between patch versions, so you can just do a rotating restart of the servers to upgrade the patch version with the original configurations, and make sure to use `--initial-cluster-state existing`.
