1 week ago We talked with the OpenStack team and they seem to OK with upgrading octavia and openstack-dashboards out of the order from the docs.
Before changing this behavior I would ask ManSol if they want to change this. It might be easier for a management perspective to have a maintenance window for upgrading things that are not suppose to affect the running VMs and other that it's necessary to make VMs migrations. That is why we separated into control-plane and data-plane applications
See https://docs.openstack.org/charm-guide/latest/admin/upgrades/openstack.html#list-the-upgrade-order - octavia must be upgraded at the end. However, COU places it in the 'control-plane' group, and upgrades it before nova-compute.
