Two Operator Instances After an Upgrade
756+
---------------------------------------
757+
758+
After you upgrade from |k8s-op-short| version 1.10 or earlier to a
759+
version 1.11 or later, your |k8s| cluster might have two instances of
760+
the |k8s-op-short| deployed.
761+
762+
Use the ``get pods`` command to view your |k8s-op-short| pods:
763+
764+
.. note::
765+
766+
If you deployed the |k8s-op-short| to OpenShift, replace the
767+
``kubectl`` commands in this section with ``oc`` commands.
768+
769+
.. code-block:: sh
770+
771+
kubectl get pods
772+
773+
If the response contains both an ``enterprise-operator`` and a
774+
``mongodb-enterprise-operator`` pod, your cluster has two |k8s-op-short|
775+
instances:
776+
777+
.. code-block:: sh
778+
:copyable: false
779+
780+
NAME READY STATUS RESTARTS AGE
781+
enterprise-operator-767884c9b4-ltkln 1/1 Running 0 122m
782+
mongodb-enterprise-operator-6d69686679-9fzs7 1/1 Running 0 68m
783+
784+
You can safely remove the ``enterprise-operator`` deployment. Run the
785+
following command to remove it:
786+
787+
.. code-block:: sh
788+
789+
kubectl delete deployment/enterprise-operator
