The basic process to update the OS should be just that. Note that the
process and the caveats may depend on the deployment tooling (tripleo,
kolla, packstack or custom one) and any customizations that you may have
done if so.

We will do some basic testing to do some advice about issues and
workarounds that you may need but note that you may hit different issues
depending on your case so the best recommendation is always test in a
non-production environment similar to production ones.

We will publish our findings.

I would separate OS update and OpenStack update. I'd try to update OS
first, and then OpenStack version.
