+`kurl.sh/pvcmigrate-destinationaccessmode` - Modifies the access mode of the PVC during migration. Valid options are - `[ReadWriteOnce, ReadWriteMany, ReadOnlyMany]`

 ## Process
 
 In order, it:
 
 1. Validates that both the `source` and `dest` StorageClasses exist
 2. Finds PVs using the `source` StorageClass
 3. Finds PVCs corresponding to the above PVs
-4. Creates new PVCs for each existing PVC, but using the `dest` StorageClass
+4. Creates new PVCs for each existing PVC
+    * Uses the `dest` StorageClass for the new PVCs
+    * Uses the access mode set in the annotation: `kurl.sh/pvcmigrate-destinationaccessmode` if specified on a source PVC
 5. For each PVC:
     * Finds all pods mounting the existing PVC
     * Finds all StatefulSets and Deployments controlling those pods and adds an annotation with the original scale
