Hi all, We are planning to upgrade our OpenStack cluster from Antelope to Caracal. We use Open vSwitch as the networking backend and do not use OVN. To avoid network disruption, we are considering upgrading OpenStack without upgrading or restarting the openvswitch-vswitchd and openvswitch-db containers. Has anyone tried this approach? Is it safe to keep the Antelope OVS version running with the Caracal Neutron-openvswitch-agent? Regards, Shawn
