To upgrade, we do this:

* upgrade kolla-ansible on the deployment host (pip install
"kolla-ansible==11.*")
* get the new version's copy of etc_examples/globals.yml
* apply settings from our own globals.yml to it
* generate and merge passwords
* take a backup of the databases with mysqldump for convenience
* kolla-ansible -i /etc/ansible/hosts upgrade --limit control

We also have a couple of postdeploy scripts we run to ensure our logos
are installed and other minor things.

We're a little behind the times though - I've just done that today
ussuri to victoria. Now continuing with '... upgrade --limit compute-r1'
etc to do compute nodes one rack at a time for safety. I wonder how much
has changed between victoria and now, and I intend to experience it over
the next few months!

HTH,
Greg.
