Testing applications

After your data, configuration, and workloads are migrated to the destination cluster, you should thoroughly test your applications before moving the cluster to production.

Testing your applications has several primary goals:
  • Ensure that your application code has been properly updated to use any new APIs in the services.
  • Ensure that you compile your applications using the Maven artifacts for the new version of CDP Private Cloud Base.
  • Ensure that your applications and queries return the expected results.
  • Ensure that your applications perform as well or better than how they performed on the source cluster. You can use Cloudera Workload XM to analyze the performance on the source cluster, and then compare those results with a similar analysis on the destination cluster.

Once testing is complete and the cluster is performing as expected, you can move the destination cluster into production and decommission the source cluster.
