-= Moving the logging aggregation solution
+= Moving the cluster logging resources
 
-[IMPORTANT]
+You can configure the Cluster Logging Operator to deploy the pods 
+for any or all of the Cluster Logging components, Elasticsearch, Kibana, and Curator to different nodes. 
+You cannot move the Cluster Logging Operator pod from its installed location. 
+
+For example, you can move the Elasticsearch pods to a separate node because of 
+high CPU, memory, and disk requirements.
+
+[NOTE]
 ====
-Cluster logging in {product-title} is not installed by default.
-You currently cannot move the logging component to another MachineSet.
+You should set your MachineSet to use at least 6 replicas.
 ====
+
+.Prerequisites
+
+* Cluster logging and Elasticsearch must be installed. These features are not installed by default.
+
+* If needed, get the name of the Cluster Logging Custom Resource in the openshift-logging project:
++
+----
+$ oc get ClusterLogging
+NAME       AGE
+instance   112m
+----
+
+.Procedure
+
+. Edit the Cluster Logging Custom Resource:
++
+----
+apiVersion: logging.openshift.io/v1
+kind: ClusterLogging
+
+....
+

+
+----
+<1> Add a `nodeSelector` parameter with the appropriate value to the component you want to move. You can use a `nodeSelector` in the format shown or use `<key>: <value>` pairs, based on the value specified for the node.
