+
+To import and export rules, use the <<managing-saved-objects, Saved Objects Management UI>>.
+
+[NOTE]
+==============================================
+Some rule types cannot be exported through this interface:
+
+**Security rules** can be imported and exported using the {security-guide}/rules-ui-management.html#import-export-rules-ui[Security UI].
+
+**Stack monitoring rules** are <<kibana-alerts, automatically created>> for you and therefore cannot be managed via the Saved Objects Management UI.
+==============================================
+
+Rules are disabled on export. You are prompted to re-enable rule on successful import.
