 ==== Scenario
 
 You want to send log files to an {es} cluster so you can visualize and analyze
 the data. This data has the following retention requirements:
 
-* When the write index reaches 50GB or is 30 days old, roll over to a new index.
+* When the primary shard reaches 50GB or the index is 30 days old, roll over to a new index.
 * After rollover, keep indices in the hot data tier for 30 days.
 * 30 days after rollover:
-** Move indices to the warm data tier.
-** Set replica shards to 1.
-** <<indices-forcemerge, Force merge>> multiple index segments to free up the
-space used by deleted documents.
+  ** Move indices to the warm data tier.
