For more benefits, check out our blog, https://www.elastic.co/blog/top-5-reasons-to-upgrade-elastic-security[Top 5 reasons to upgrade Elastic Security]. Also, it's important to ensure that your deployment is fully maintained and supported. For more information, refer to https://www.elastic.co/support/eol[Elastic's Product End of Life Dates]. + +[float] +=== Plan for your upgrade + +Before upgrading to {elastic-sec} 8.x, consider the following recommendations: + +* Plan for an appropriate amount of time to complete the upgrade. Depending on your configuration and the size of your cluster, the process can take up to a week to complete. + +* Open a https://support.elastic.co[support case] with Elastic to alert our Elastic Support team of your system change. If you need additional assistance, https://www.elastic.co/consulting[Elastic Consulting Services] provides the technical expertise and step-by-step approach for upgrading your Elastic deployment. + +* Choose a version to upgrade to. We recommend the latest minor and patch version. Be sure to upgrade your development or non-production deployment to the same version as your production deployment. + +* Ensure that you have {kibana-ref}/xpack-monitoring.html[stack monitoring] enabled in {kib}. Take note of your current index and search rate. + +* Review your selected version's features, Elastic connectors, integrations, and detection rules to determine if you can replace any customized content with out-of-the-box functionality. This can help reduce your workload and the complexity of your upgrade. + +* If your organization sends alerts (formerly known as signals) to an external SOAR (security orchestration, automation, and response) platform, you may need to change your workflows to accommodate the new <> used in 8.x. + +* Review release notes, deprecations, and breaking changes for {security-guide}/release-notes.html[{elastic-sec}], {ref}/es-release-notes.html[{es}], {kibana-ref}/release-notes.html[{kib}], and, if applicable, {fleet-guide}/release-notes.html[{fleet} and {agent}], {beats-ref}/release-notes.html[{beats}], and {logstash-ref}/releasenotes.html[{ls}].

Do a software version inventory across your entire Elastic deployment, including {es}, {kib}, {agent}, {beats}, and {ls}. + +. If you're running any versions earlier than 7.17, you must first upgrade them all to the latest 7.17.x patch release before upgrading to 8.x.

Note that alerts in 8.x are written using the `kibana_system` user instead of the `current user`, so any user-modified ingest pipelines configured against the alert index (this is uncommon) will use the `kibana_system` user privileges, which may break your ingest pipeline. If you encounter this issue, please do not update your ingest pipeline. Instead, contact your Elastic Support rep for assistance. + +. If you're upgrading to {stack} 8.0.x or 8.1.x, you must update your Elastic prebuilt detection rules _while your {stack} is at 7.17_. To update Elastic prebuilt rules, go to the *Rules* page and select *Update _x_ Elastic prebuilt rules*. This ensures that you have the latest prebuilt rules before upgrading the {stack}. ++ +NOTE: This step isn't required if you're upgrading to {stack} 8.2 or later. If you're unable to update your prebuilt rules at 7.17, upgrade to {stack} 8.2 or later. + +. Run the {kibana-ref}/upgrade-assistant.html[Upgrade Assistant].
