I'm bumping this to a blocker for 1.7.0. Plans created earlier than 1.7 are not going to have this annotation, and neither will those that are created on the cli.
Verified with MTC 1.7.0 (pre-stage) metadata_nvr: openshift-migration-operator-metadata-container-v1.7.0-33 image: registry.redhat.io/rhmtc/openshift-migration-controller-rhel8@sha256:c08211e7fa12e8a12ea07ed0f31bf24bdd4cc95b166a34d826e3240a0534e622 Migration plans page is not going blank when the migplan is created without migration type annotation. Moving this to Verified status.
