Find the Sweet Spot of Splunk Enterprise Upgrades

Splunk adds and updates features and functions to Splunk Enterprise regularly to keep pace with innovation and reduce risk. In fact, Splunk releases these updates on the Splunk Cloud platform continually.

For on-prem customers, Splunk releases two levels of software updates to Splunk Enterprise:

• Major "x." and minor "x.x" releases include new and updated features and functions, updated platform elements, and cumulative bug fixes. Splunk issues major and minor releases on average twice per year.
• Maintenance "x.x.x" releases include bug fixes and minor updates within a major release interval. Splunk issues maintenance releases several times per year.

On-prem customers benefit from the continual updates to the Cloud platform because features, functions, and updates are thoroughly road-tested and hardened when they are released in a major version update.

So if you have an on-prem Splunk Enterprise implementation, the best practice is to upgrade as often as you can, but at least once per year. Then establish a regular upgrade cadence so you can keep pace with all major and maintenance updates Splunk releases. If you are on a later Splunk Enterprise version, maintenance updates are straightforward and non-disruptive to perform.

If Splunk issues a maintenance release during your upgrade planning cycle, we strongly recommend that you make the latest release the target of your upgrade.

The key is to be proactive. Don't wait until you encounter a bug or reach the end of the version support window.

More Upgrade Tips

• Find which versions of Splunk software are currently supported, and learn their end-of-support window in the Splunk Software Support Policy.
• Good news if you have a clustered architecture: rolling upgrade features available since Splunk 7.1 have taken a lot of tedium out of regular upgrades. For details, see "Perform a rolling upgrade of a search head cluster" in the Splunk Enterprise Distributed Search manual, and “Perform a rolling upgrade of an indexer cluster” in the Managing Indexers and Clusters of Indexers manual.
• If you never want to worry about upgrading your Splunk platform again, migrate to Splunk Cloud and let the Splunk experts take care of upgrades, infrastructure, and maintenance for you. To learn more, contact your Splunk sales representative, or visit Splunk Cloud on the Splunk website.
• Watch the Splunk Answers post, "How often should I upgrade Splunk Enterprise?," for updates and feedback about establishing a regular upgrade cadence.
