Resolved Issue in Release 23.5.21
Container cluster reporting "Virtual service is still active on a workload after upgrading to "clusterMode: migrateLegacyToClas" (E-114727)
After a non-CLAS (legacy) deployment was upgraded to CLAS mode, existing container clusters running multiple ClusterIP virtual services each went into an Error Status, with each cluster detail page also displaying a "Virtual service is still active on a workload" message.
