High-level upgrade steps

You need to upgrade the Data Lake and Cloudera Data Hub clusters in your environment separately. During the 7.3.2 upgrade the operating system (OS) version is automatically upgraded to RHEL 9.6 and the JDK version is automatically upgraded to 17.

Use the following steps to directly upgrade to Cloudera Runtime 7.3.2:

Upgrade Data Lake clusters to Cloudera Runtime to 7.3.2 - includes OS and JDK upgrade
Upgrade Cloudera Data Hub clusters to 7.3.2 - includes OS and JDK upgrade

important

Each of these operations has its own prerequisites and postrequisites so in addition to the actual upgrade steps, the prerequisites and postrequisites need to be performed as well.
You will need to upgrade all Data Lakes and Cloudera Data Hub clusters separately, first the Data Lakes and then each Cloudera Data Hub cluster.
For Data Lakes, the Runtime and OS upgrade is performed in one step. For Cloudera Data Hub clusters, the Runtime and OS upgrade is performed in one step with the exception of the following scenarios, where the OS upgrade is only performed automatically for the Gateway nodes:
- When upgrading a Cloudera Operational Database cluster
- When rolling upgrade is requested for large clusters (more than 20 nodes)
You can perform each upgrade operation either from the Upgrade UI of the respective cluster or using the CDP CLI.
The upgrade user interface in the Cloudera Management Console shows you the next Data Lake and Cloudera Data Hub upgrade step available, so you can refer to it as a guideline.
