Upgrade Cloudera Runtime to 7.3.2 for the Data Lake clusters

As a first step in the Cloudera on cloud upgrade, you need to upgrade the Cloudera Runtime version to 7.3.2 and the OS version to RHEL 9 for the Data Lake cluster in your Cloudera environment.

Before upgrading to Cloudera Runtime 7.3.2, verify that your Data Service is compatible with the latest version of Cloudera Runtime. For more information, see the following documentations:

Once Runtime 7.3.2 (Runtime upgrade, OS: redhat8) is available to select from the Upgrade UI, select it and run Validate and Prepare.
Once Validate and Prepare completes, return to this page, select 7.3.2 (Runtime upgrade) again and run Upgrade.
