Understanding the Cloudera Data Services on premises upgrade process using OpenShift Container Platform

Upgrading Cloudera Data Services on premises requires coordinating updates with the corresponding OpenShift Container Platform (OCP) version upgrades.

All upgrades to Cloudera Data Services on premises 1.5.5 SP2 must use a minimum version of OpenShift Container Platform 4.16. Intermediate OpenShift Container Platform versions are tested with existing workloads, but Cloudera recommends selecting a supported pvc-ocp version for a given Cloudera Data Services on premises release based on the Cloudera Support Matrix.

important

Ensure that the OpenShift namespace name is 29 characters or less. Do not proceed with the upgrade process if the namespace name is 30 or more characters in length.
You must upgrade Cloudera Manager to version 7.13.1.700 before beginning the multi-hop upgrade from Cloudera Data Services on premises 1.5.4 SP2 or 1.5.5 to 1.5.5 SP2. To complete this process, you must first upgrade to Cloudera Data Services on premises 1.5.5 SP1 (if you are using Cloudera AI Workbench, then you must upgrade Cloudera AI after upgrading to Cloudera Data Services on premises 1.5.5 SP1) and then upgrade to version Cloudera Data Services on premises 1.5.5 SP2 and then Cloudera AI Workbench.
