-Although logging version 5.9 and higher supports schema v12, v13 is recommended.
+* Although logging version 5.9 and higher supports schema v12, v13 is recommended.
+
+* Stream-based retention does not manage the retention for stored logs. You can configure global retention periods for stored logs to a supported maximum of 30 days in your object storage.

+.Prerequisites 
+
+* You have administrator permissions.
+* You have installed the {loki-op}.
+* You have installed the {oc-first}.
+
+.Procedure

 . To enable stream-based retention, create a `LokiStack` CR:

-.Example global stream-based retention for AWS
