+title: Application Migration
+---
+
+When there are multiple Kubernetes clusters that are configured to connect
+to the same external Ceph cluster, the applications running in each K8s cluster
+will be storing the data in the same central Ceph cluster.
+In this setup, applications can be migrated to another cluster without requiring any data movement.
+For example, an application may need to migrate if one application cluster is becoming
+overloaded or if there is an outage in a cluster.
+
+Consider the following diagram to illustrate two applications available for migration:
+
+- App A has an RBD RWO PVC in Cluster 1 that can be migrated to Cluster 2
+- App B has a CephFS RWX PVC in Cluster 1 that can be migrated to Cluster 2
+
+The external Ceph cluster stores the data, thus no data movement is necessary when the applications
+are migrated.
+

+
+### Defining Applications for Migration
+
+Configuring an application to migrate between clusters requires the following:
+
+- One external Ceph cluster that is accessible from the K8s application clusters.
+    The Ceph cluster could be configured by Rook with [host networking](../../CRDs/Cluster/network-providers.md#host-networking),
+    or configured with other tools such as cephadm.
+- The application clusters must configure Rook to connect to the same
+    [external cluster](../../CRDs/Cluster/external-cluster/external-cluster.md),
+    with access to the same Ceph pool, radosnamespace (RBD), and/or subvolumegroup (CephFS).
+- For each application
+    - Create the application and its PVC in the first cluster
+    - Backup the PV and modify the PV for creation in another cluster
+
+After creating the application, there will be a PV that is bound to the application's PVC.
+Find which PV is bound to the application's PVC. For example:
+
+```command
+# replace "rbd-pvc" with the actual pvc name
+$ kubectl get pvc rbd-pvc -o yaml | grep volumeName
+
+  volumeName: pvc-2dc3e161-bda2-4b42-956a-42a69a717979
+```
+
+Retrieve the PV and save to a file:
+
+```command
+# This command removes the cluster-specific `uid` and `resourceVersion` fields
+kubectl get pv pvc-2dc3e161-bda2-4b42-956a-42a69a717979 -o yaml | egrep -v " uid: | resourceVersion: " > application-pv.yaml
+```
+
+Now the PV can be created in another cluster when the application needs to be migrated.
+
+!!! tip
+    The PV could be backed up with tools such as Velero. This doc is only attempting to show
+    how the application can be migrated without external tools.
+
+!!! tip
+    Consider provisioning volmes from a storage class with `reclaimPolicy: Retain` to prevent
+    accidental deletion of a volume in one cluster while the other cluster is still consuming
+    the volume.
+
+### Migrating an Application
+
+When the application needs to be migrated to another cluster:
+
+1. Scale down the application in the first cluster.
+2. If an RWO PVC, ensure the application is stopped and is not capable of accidentally connecting
+    to Ceph. RBD volumes have no protection against corruption from multiple instances
+    of an application accessing the same volume across clusters. Either confirm the
+    volume attachment has been removed in the original cluster, or block-list the
+    original cluster from connecting to the Ceph cluster. This requirement
+    does not apply to CephFS RWX volumes, as CephFS allows multiple clients.
+3. Create the PV that was prepared in the previous section.
+    - If the application will be created in a different namespace or with a different PVC
+        name from the original cluster, update the corresponding properties in the `claimRef`.
+    - `kubectl create -f application-pv.yaml`
+4. Create or scale up the application and its PVC in the new cluster.
+5. Confirm that the application PVC is bound to the PV created in step 3.
