+= Limitations of managing imported hosted clusters
+
+Hosted clusters are automatically imported into the local {mce}, unlike a standalone {product-title} or third party clusters. Hosted clusters run some of their agents in the _hosted mode_ so that the agents do not use the resources of your cluster.
+
+If you choose to automatically import hosted clusters, you can update node pools and the control plane in hosted clusters by using the `HostedCluster` resource on the management cluster. To update node pools and a control plane, see "Updating node pools in a hosted cluster" and "Updating a control plane in a hosted cluster".
+
+You can import hosted clusters into a location other than the local {mce-short} by using the {rh-rhacm-first}. For more information, see "Discovering {mce} hosted clusters in Red Hat Advanced Cluster Management".
+
+In this topology, you must update your hosted clusters by using the command-line interface or the console of the local {mce} where the cluster is hosted. You cannot update the hosted clusters through the {rh-rhacm} hub cluster.
