+[#ejection-policy-without-restart]
+https://jira.issues.couchbase.com/browse/MB-67082[MB-67082] Allow eviction policy to be changed without bucket restart::
+The new `noRestart` parameter for the `/pools/default/buckets/{BUCKET-NAME}` REST API lets you change the ejection policy of a Couchbase bucket without automatically restarting it.
+If you prevent the restart, perform one of the following:
++
+--
+* A swap rebalance 
+* On each data node, perform a graceful failover, then either a delta (when not performing a storage backend migration) or full recovery followed by a rebalance.
+--
++
+Either of these procedures lets you avoid the downtime associated with restarting the bucket.
+For more information, see xref:manage:manage-buckets/change-ejection-policy.adoc[].
+
++
+This setting is useful when you migrate a bucket to a new storage engine that would benefit from a new ejection policy.
+For example, you should consider changing a bucket's ejection policy to Full Ejection when migrating a bucket  to the xref:learn:buckets-memory-and-storage/storage-engines.adoc#storage-engine-magma[Magma storage engine].
+Using the `noRestart` parameter, you can change the ejection policy at the same time you migrate the bucket to the new storage engine.
+See xref:manage:manage-buckets/migrate-bucket.adoc[] for more information.

+[#ejection-ephemeral-buckets]
+https://jira.issues.couchbase.com/browse/MB-64104[MB-64104] Allow changing the ejection policy of ephemeral buckets::
+You can now change the ejection policy of an ephemeral bucket using the Couchbase Server Web Console and the REST API. 
+Unlike Couchstore buckets, changing the ejection policy of an ephemeral bucket does not require a bucket restart or other additional steps.
+For more information, see xref:manage:manage-buckets/change-ejection-policy.adoc[].
