      Expected results:

          "During the migration, when the cluster is running with both OVN Kubernetes and OpenShift SDN,Multicast and Egress IP will be temporarily disabled for both CNIs. Egress Firewall shall remain functional, as the implementation of this feature is per-node-based in both CNIs.

      During the migration, when the cluster is running with both OVN Kubernetes and OpenShift SDN,

      • Multicast and Egress IP will be temporarily disabled for both CNIs.
      • Egress Firewall shall remain functional, as the implementation of this feature is per-node-based in both CNIs.
