Upgrading IBM Maximo Application Suite by using the channel subscription method

Note: The Maximo® Application Suite upgrade policy supports n-1 versions within a cluster. This means that you can upgrade directly from the version immediately preceding the current one. For example, if the current version of Maximo Application Suite is 9.1, you can upgrade directly from 9.0 in a cluster.

Channel subscription upgrades of IBM® Maximo Application Suite involve setting the subscription channel for your installed Maximo Application Suite operator, ensuring that the upgrade is approved, and updating the applications.

Before you begin

Before you can upgrade the Maximo Application Suite, you must complete the prerequisite steps, such as deleting incompatible applications, installing the IBM Certificate Manager service, and upgrading your Cloud Pak for Data System.

Note: If IBM Maximo Manage is installed and the Anywhere component is enabled as part of the Maximo Manage 8.4 installation, and when you upgrade to Maximo Manage 8.5. Anywhere is automatically removed as a component.

About this task

To upgrade your Suite instance, you set the subscription channel for your installed Maximo Application Suite operator in Red Hat® OpenShift® and ensure that the upgrade is approved.

Procedure

In the Red Hat OpenShift web console, in your installed Suite operator, set the subscription channel, such as to either 8.x.x or 8.x.

For example, set the subscription channel to either 8.9.x or 8.x.

For more information, see Upgrading installed Operators in the Red Hat OpenShift documentation.

The upgrade will begin after it is approved. The approval strategy that is configured in your Maximo Application Suite operator's subscription determines how upgrades are approved.

If the strategy is set to Manual, you can manually approve the upgrade in the Subscription tab. If the strategy is set to Automatic, the upgrade is approved and completes automatically.

If the automatic approval strategy is set to On, when new application updates are available, they are added to the channel and updated in your Maximo Application Suite instance automatically. If the strategy is set to Off, when new application updates are available, you receive a notification, and you can manually approve the updates.

What to do next

When the upgrade is complete, you can log in to the Maximo Application Suite Administration page and continue with the upgrade process by updating applications.
