Hi Wodel, We haven't done it yet (but will need to soon since we're on Train and stable/train branch is gone!) but this looks like a good place to start: https://docs.openstack.org/kolla-ansible/train/user/operating-kolla.html I'm not sure about this, but it came up in a web search and might help too: https://www.reversengineered.com/2019/05/10/upgrading-kolla-ansible-for-depl...

Hi,
What are the steps of upgrading an openstack platform when the upgrade involves:
- OS upgrade: how to perform the upgrade? What type of node to upgrade first? Controllers, network or compute?
- Ceph storage when using HCI deployment?
Just general steps.
