Upgrade Splunk add-ons and applications:

Verify the upgrade:

  2. For distributed deployment, use Monitoring Console to verify all Splunk Enterprise components.
  3. Review resource utilization for all components and compare to the benchmarked system health prior to the upgrade.
  4. Confirm all components are available.
  5. Confirm that the license master machine works properly, and all indexers are connected to it.
  6. Confirm that the cluster master operates normally and that cluster peers are connecting properly.
  7. Confirm that the search tier operates normally, and that search and indexers communicate properly.
  8. User the Monitoring Console to verify search head cluster state and individual cluster peer nodes.
  9. Confirm that all indexer cluster nodes are communicating with the cluster master.

Finally, upgrade the Universal forwarder if the existing version is not compatible with the latest version of Splunk enterprise. Don’t forget to perform cleanup after the upgrade.
