+= Upgrading scenarios for hosted control planes
+
+Consider the following information before you upgrade:
+
+* You use bare metal as a management cluster platform.
+
+* You use Agent or KubeVirt as a Hosted cluster platform.
+
+[NOTE]
+====
+The management cluster is based on the installer-provisioned infrastructure (IPI).
+====
+
+Review the following scenarios:
+
+* While running your management cluster on {product-title} 4.14, you can upgrade the multicluster engine (MCE) version from 2.4 to 2.5. Then, you can upgrade your hosted cluster and node pools from {product-title} 4.14 to {product-title} 4.15.
+
+* If you want to upgrade management cluster, MCE, hosted cluster, and node pools to their latest versions:
+
+** Upgrade your management cluster from {product-title} 4.14 to {product-title} 4.15
+** Upgrade the MCE version from 2.4 to 2.5
+** Upgrade your hosted cluster and node pools from {product-title} 4.14 to {product-title} 4.15
