There are thee KB articles that are highly relevant to the SDN to OVN migration and would be highly beneficial if they could be linked in our docs.

In the offline migration section:
https://docs.redhat.com/en/documentation/openshift_container_platform/4.16/html/networking/ovn-kubernetes-network-plugin#nw-ovn-kubernetes-migration-about_migrate-from-openshift-sdn
we should link the best practices KB: https://access.redhat.com/articles/7076160

In the limited live migration section:   
https://docs.redhat.com/en/documentation/openshift_container_platform/4.16/html/networking/ovn-kubernetes-network-plugin#nw-ovn-kubernetes-migration-about_migrate-from-openshift-sdn
we should link the LLM KB: https://access.redhat.com/solutions/7057169

In the "about networking" section at the beginning:
https://docs.openshift.com/container-platform/4.16/networking/about-networking.html
we should link the SDN deprecation notice: https://access.redhat.com/articles/7065170
