+*Details* +
+Directly accessing system indices is deprecated. In {es} 8.0, you must add the
+`allow_restricted_indices` permission set to `true` on a user role to access
+system indices. Refer to 
+{ref}/defining-roles.html#roles-indices-priv[indices privileges] for
+information on adding this permission to an index privilege.
+
+*Impact* +
+Accessing system indices directly results in warnings in the header of API 
+responses and in the deprecation logs. Use {kib} or the associated feature's
+{es} APIs to manage the data that you want to access. While it's still possible 
+to access system indices in {es} 7.16, they are reserved only for internal use
+by Elastic products and should not be accessed directly.
