Upgrading the IBM MQ Operator using the Red Hat OpenShift web console

The IBM® MQ Operator can be upgraded using the Operator Hub.

Before you begin

Note: The latest CD version of the IBM MQ Operator is 3.1.3. The latest LTS version of the IBM MQ Operator is 2.0.29. For the latest IBM MQ Operator release notes, see Release history for IBM MQ Operator.

Procedure

Review Version support for the IBM MQ Operator to determine which operator channel to upgrade to.
Apply latest Catalog source.
If you are using the IBM MQ specific catalog source (all air-gap installs), rather than the ibm-operator-catalog, you must apply the catalog source for your IBM MQ version.

Follow the instructions in Adding catalog sources to a cluster.
Note: If you have already completed the operator install step for air-gap Mirror images (air-gap only), you only have to complete the step that applies the catalog source. For example:
```
oc apply -f ~/.ibm-pak/data/mirror/${OPERATOR_PACKAGE_NAME}/${OPERATOR_VERSION}/catalog-sources.yaml
```
Upgrade the IBM MQ Operator. New major/minor IBM MQ Operator versions are delivered through new Subscription Channels. To upgrade your Operator to a new major/minor version, you will need to update the selected channel in your IBM MQ Operator Subscription.

  All installed Operators in the specified project are displayed.
2. Select the IBM MQ Operator
3. Navigate to the Subscription tab
4. Click the Channel
  The Change Subscription Update Channel window is displayed.
