Upgrading Red Hat OpenShift Container Platform on AWS (OCP 4.14)

Deployment options: Netezza Performance Server for Cloud Pak for Data

After you upgraded infrastructure components, Cloud Pak for Data and Netezza Performance Server for Cloud Pak for Data upgrade Red Hat OpenShift Container Platform (from version 4.12.26 to 4.14.29).

Before you begin

  1. Determine your Red Hat OpenShift Container Platform upgrade path.
    1. Verify your current Red Hat OpenShift Container Platform version.
      oc version
      Example:
      oc version

Client Version: 4.12.37 
Server Version: 4.12.26 
Kubernetes Version: v1.25.11+1485cc9
    2. Find the suggested upgrade path by using the the Red Hat OpenShift Container Platform upgrade path tool.

      If you want to upgrade from 4.12 to 4.14, the suggested upgrade path is 4.12.26 > 4.13.43 > 4.14.29.

      You must find your upgrade path before every upgrade.

      If you want to upgrade from versions earlier than 4.12, see Upgrading Netezza Performance Server for Cloud Pak for Data to 11.2.1.6-IF1.

  2. If you deployed any custom applications that use the deprecated APIs, you must update these applications to use the suggested APIs prior you upgrade Red Hat OpenShift Container Platform. If you do not update them, they do not work after the upgrade.
