+
+    The ``system-local-ca`` |TLS| certs and key are shared between
+    SystemController and subclouds in DC systems. Considering this, the
+    overrides for the |RCA|/|ICA| certs and key are not applicable to
+    subclouds, but the leaf certificates can still be configured with the
+    override ``system_platform_certificate`` in separate ways.
+
+For more info about the overrides, look into the inventory parameters described
+in :ref:`migrate-platform-certificates-to-use-cert-manager-c0b1727e4e5d`.
