Upgrade Cloudera Runtime version of Cloudera Data Hub clusters to 7.3.1

Once the Data Lake Cloudera Runtime version has been upgraded to 7.3.1 and simultaneously, the OS has been upgraded to RHEL 8.10, the Cloudera Runtime version of each Cloudera Data Hub cluster needs to be upgraded to 7.3.1.

1. Once Runtime 7.3.1 (Runtime upgrade) is available to select from the Upgrade UI, select it and run Validate and Prepare.
2. Once Validate and Prepare completes, return to this page, select 7.3.1 (Runtime upgrade) again and run Upgrade.
  tip
  When upgrading a Cloudera Data Hub cluster,allocate 90-120 minutes (as you will be performing this upgrade in two steps).
