|prod| |prod-ver| contains the installer for Trident 21.04, but installations
|

that have been upgraded from the previous |prod| version and were configured
|

to use a NetApp backend will still be running Trident 20.04 after the upgrade
|

to |prod| |prod-ver|.

.. note::
|
|
|
|
In the table above, the client version refers to the binary
|
|
(``tridentctl``) and the server version refers to the services installed in
|
|
Kubernetes.
|
|
|
|
This difference between versions only occurs during the upgrade, as the
|
|
client version will be upgraded, but the server version will be the current
|
|
version at this point.

Before upgrading Kubernetes to version 1.19, the running version of Trident
|
|
must be updated to 21.04. This will not disrupt any containers that are already
|
|
running, but will cause a brief outage to the NetApp Trident control plane.
|
|
|
|
The steps are as follows:
|
|
|
|
#. Locate the ``localhost.yaml`` file that was used originally to install
|
|
Trident, as described in :ref:`Configure an External NetApp Deployment as
|
|
the Storage Backend
|
|
<configure-an-external-netapp-deployment-as-the-storage-backend>`.
|
|
|
|
#. Add the line ``trident_force_reinstall: true`` to the file.
|
|
|
|
#. Run the ``install_netapp_backend.yml`` playbook again as per Run Playbook
|
|
step of section :ref:`Configure an External NetApp Deployment as the
|
|
Storage Backend
|
|
<configure-an-external-netapp-deployment-as-the-storage-backend>`.
|
|
|
|
#. On completion, verify that the Trident server version has been updated:
|
|
|
|
.. code-block:: none
|
|
|
|
[sysadmin@controller-0 trident(keystone_admin)]$ tridentctl -n trident version
