openshift-sdn is no longer supported for new installs as of 4.15, and it will be completely removed from OpenShift in 4.17.

Your component currently has one or more CI jobs that use openshift-sdn:

ci-operator/config/openshift/kubernetes-nmstate/openshift-kubernetes-nmstate-master.yaml
  e2e-handler-sdn-ipv4
  e2e-handler-sdn-ipv4-nightly-periodic

These jobs will need to be removed or migrated to ovn-kubernetes by OCP 4.17. In some cases, if you were not intentionally testing openshift-sdn, it may make sense to start migrating these jobs in 4.15. You may want to split this bug into multiple bugs for different OCP versions.

Component-specific notes:

• e2e-handler-sdn-ipv4 and e2e-handler-sdn-ipv4-nightly-periodic both have corresponding identical ovn-based jobs, so they can just go away in 4.17. It is presumably useful to keep testing that nmstate+sdn still works correctly in 4.15 and 4.16.
