+# Upgrade from Elastic AI SOC Engine to {{elastic-sec}} to access additional features
+
+This page describes how to upgrade an {{sec-serverless}} project from the Elastic AI SOC Engine (EASE) feature tier to the Security Analytics Essentials or Security Analytics Complete feature tiers.
+
+## Why upgrade?
+EASE provides a small subset of the features available on other {{sec-serverless}} feature tiers. It's designed to add a layer of AI features onto your existing SOC software stack. In contrast, {{elastic-sec}} provides a full set of SOC capabilities including many additional ways to ingest data, prebuilt and customizable detection rules, response actions, integrated threat intelligence, runtime protection, data visualization, and more. 
+
+For a full breakdown of the features available in the Security Analytics Essentials and Security Analytics Complete feature tiers, refer to [Elastic Security Serverless pricing](https://www.elastic.co/pricing/serverless-security).
+
+:::{important}
+The AI features present in EASE are not available on the Essentials tier. 
+:::
+
+
+## How to upgrade from EASE to other feature tiers
+
+1. Log in to the [{{ecloud}} console](https://console.qa.cld.elstc.co/).
+2. Find the project you wish to upgrade on the list of serverless projects, and click **Manage**.

+   :::
+
+4. Select either the **Security Analytics Essentials** or **Security Analytics Complete** options, and select any desired add-on options. Click **Save**. 
+
+You can return to this page at any point to switch between Essentials and Complete and change your add-on selections.
+However, once you upgrade from EASE to another product tier, you cannot revert or downgrade the project back to EASE. You can always create another new project of any tier.
+
+## What to do after upgrading an EASE project
+
+When you upgrade an EASE project, you gain access to all the {{elastic-sec}} capabilities included in your selected [feature tier](https://www.elastic.co/pricing/serverless-security). To learn more about what {{elastic-sec}} can do and how to use it, refer to [Get started with {{elastic-sec}}](/solutions/security/get-started.md).
