 = Scaling down director Operator resources
 
 Before you migrate your databases to the control plane, you must scale down and remove OpenStack director Operator (OSPdO) resources in order to use the {rhos_long} resources.
 
+You must perform the following actions:
+
+* Dump selected data from the existing {OpenStackShort} {rhos_prev_ver} cluster. You use this data to build the custom resources for the data plane adoption.
+* After you extract and save the data, remove the OSPdO control plane and operator.
+
 .Procedure
+. Download the NIC templates:
++
+----
+    # Make temp directory if doesn't exist
+    mkdir -p temp
+    cd temp
+    echo "Extract nic templates"
+    oc get -n "${OSPDO_NAMESPACE}" cm tripleo-tarball -ojson | jq -r '.binaryData."tripleo-tarball.tar.gz"' | base64 -d | tar xzvf -
+    # Revert back to original directory
+    cd -
+----
+. Get the SSH key for accessing the data plane nodes:
++
+----
+    # Make temp directory if doesn't exist
+    mkdir -p temp
+    # Get the SSH key from the openstackclient (osp 17)
+    # to be used later to create the SSH secret for dataplane adoption
+    $OS_CLIENT cat /home/cloud-admin/.ssh/id_rsa > temp/ssh.private
+    $OS_CLIENT cat /home/cloud-admin/.ssh/id_rsa.pub > temp/ssh.pub
+    echo "SSH private and public keys saved in temp/ssh.private and temp/ssh.pub"
+----
+. Get the OVN configuration from each Compute node role, `OpenStackBaremetalSet`. This configuration is  used later to build the `OpenStackDataPlaneNodeSet`(s). Repeat the following step for each `OpenStackBaremetalSet `:
++
+----
+    # Make temp directory if doesn't exist

Scale down the {rhos_acro} OpenStack Operator `controller-manager` to 0 replicas and temporarily delete the `OpenStackControlPlane` `OpenStackClient` pod, so that you can use the OSPdO `controller-manager` to clean up some of its resources.
