+Intel Multi-driver Version
+==========================
+
+.. rubric:: |context|
+
+This sections describes how to change the Intel driver bundle version.
+Currently there are 2 CVL versions available:
+
+.. warning::
+
+    The |NIC| firmware (NVM) has to align with one of the selected driver
+    bundles listed below.
+
+-   ``cvl-4.0.1`` (default)
+      - ice: 1.9.11 / Required NVM/firmware: 4.0
+      - i40e: 2.20.12 / Required NVM/firmware: 8.70
+      - iavf: 4.5.3
+
+-   ``cvl-2.54`` (legacy)
+      - ice: 1.5.8.1 / Required NVM/firmware: 2.54
+      - i40e: 2.14.13 / Required NVM/firmware: 8.21
+      - iavf: 4.0.1
+
+Change Intel Multi-driver Version
+---------------------------------
+
+On initial installation, the system will use the default driver bundle version
+which is ``cvl-4.0.1``. The chosen driver bundle will be applied subsequently
+as part of the deployment configuration, if specified.
+
+When there is no driver bundle specified as part of deployment, the system will
+continue to use the default driver bundle.
+
+To change the driver bundle to the legacy version, add the system service
+parameter ``intel_nic_driver_version`` to ``cvl-2.54``.
+
+.. code-block:: none
+
+    ~(keystone_admin)$ system service-parameter-add platform config intel_nic_driver_version=cvl-2.54
+
+
+To change the driver bundle back to the default version, there are two options:
+
+#.  Modify the system service parameter ``intel_nic_driver_version`` to
+    ``cvl-4.0.1``.
+
+    .. code-block:: none
+
+        ~(keystone_admin)$ system service-parameter-modify platform config intel_nic_driver_version=cvl-4.0.1
+
+#.  Apply the service parameter change.
+
+    .. code-block:: none
+
+        ~(keystone_admin)$ system service-parameter-apply platform
+        Applying platform service parameters
+
+#.  Remove the system service parameter ``intel_nic_driver_version``.
+
+.. code-block:: none
+
+    ~(keystone_admin)$ system service-parameter-list --service platform --section config --name intel_nic_driver_version
+    +--------------------------------------+------------+---------+---------------------------+-----------+-------------+----------+
+    | uuid                                 | service    | section | name                      | value     | personality | resource |
+    +--------------------------------------+------------+---------+---------------------------+-----------+-------------+----------+
+    | 84306212-d96d-4a2a-8cc0-2d48781e006c | platform   | config  | intel_nic_driver_version  | cvl-2.54  | None        | None     |
+    +--------------------------------------+------------+---------+---------------------------+-----------+-------------+----------+
+    ~(keystone_admin)$ system service-parameter-delete 84306212-d96d-4a2a-8cc0-2d48781e006c
+
+To apply the service parameter change, all hosts need to be locked and
+unlocked, using the following commands for each host depending on the deployed
+configuration:
+
+For |AIO-SX| deployments:
+
+.. code-block:: none
+
+    ~(keystone_admin)$ system host-lock controller-0
+    ~(keystone_admin)$ system host-unlock controller-0
+
+For |AIO-DX| and Standards deployments, after controller-1 is locked/unlocked
+swact controller-0 to make controller-1 the active node. The next set of
+commands are executed on controller-0 node:
+
+.. code-block:: none
+
+    ~(keystone_admin)$ system host-lock controller-1
+    ~(keystone_admin)$ system host-unlock controller-1
+    ~(keystone_admin)$ system host-swact controller-0
+
+On controller-1, after controller-0 is locked/unlocked swact controller-1 to go
+back to controller-0 as the active node. The next set of commands are executed
+on controller-1 node:
+
+.. code-block:: none
+
+    ~(keystone_admin)$ system host-lock controller-0
+    ~(keystone_admin)$ system host-unlock controller-0
+    ~(keystone_admin)$ system host-swact controller-1
+
+For each worker node in the configuration execute the commands from
+controller-0:
+
+.. code-block:: none
+
+    ~(keystone_admin)$ system host-lock worker-0
+    ~(keystone_admin)$ system host-unlock worker-0
+
+To verify the current Intel driver version use ``ethtool -i`` on the desired
+Intel network interface. For example:
+
+.. code-block:: none
+
+    ~(keystone_admin)$ ethtool -i ens785f0 | egrep '^(driver|version):'
+    driver: i40e
+    version: 2.20.12
+
+Upgrades
+--------
+
+For an upgrade, the default drivers will be configured after the upgrade.
+To set the legacy drivers for an upgrade, set the driver bundle on
+controller-0 prior to the upgrade using the following commands:
+
+.. code-block:: none
+
+    ~(keystone_admin)$ system service-parameter-add platform config intel_nic_driver_version=cvl-2.54 --resource platform::compute::grub::params::g_intel_nic_driver_version
+    ~(keystone_admin)$ system service-parameter-apply platform
+
+Backup and Restore
+------------------
+
+In case a Backup and Restore is performed, after unlocking the host during a
+restore operation, the system will be configured with the correct multi-driver
+version, but the drivers will be loaded to the default version.
+
+To load the drivers to the correct configured version a second host-unlock will
+be needed.
