-Some older indices might be managed by {ref}/data-stream-lifecycle.html[data stream lifecycle (DSL)] if a cluster is upgraded to 8.17.
+Indices created in 8.15.x and 8.16.x might be managed by {ref}/data-stream-lifecycle.html[data stream lifecycle (DSL)].
+More details are available in <<apm-release-notes-8.15>>.
+By default, new indices created in 8.17 are managed by ILM.
 More details are available in <<apm-release-notes-8.17>>.
+If you have indices managed by DSL, any custom DSL settings that you specified will _not_ automatically apply to the new indices managed by ILM.
+Instead, you can replicate custom DSL settings in ILM using this guide.
