Red Hat OpenShift 6.0 requires migrating from Elasticsearch to Loki for logging functionality. Loki offers better performance through log labels instead of indexing full log lines, supports multi-tenancy, and uses fewer resources. The migration process involves installing LokiStack, disconnecting Elasticsearch and Kibana from ClusterLogging management, switching the log store configuration, and enabling the OpenShift console plugin for log visualization. Both systems run in parallel during transition, with old logs remaining in Elasticsearch/Kibana while new logs flow to LokiStack.
