Before upgrading, download and install a newer version of Endpoint Upgrade Assistant if one is available. Endpoint Upgrade Assistant notifies you when a newer version is available. The latest version includes support for the latest Trellix product versions and features.

Endpoint Upgrade Assistant is installed automatically with some versions of ePO - On-prem. If it isn't already installed in your environment, you need to install it on the ePO - On-prem server.

During installation, the extension is installed on the ePO - On-prem server. Also, the Endpoint Upgrade Assistant client package is checked in to all branches of ePO - On-prem, so that you can deploy upgrades from any branch. During upgrades, Upgrade Automation is deployed with the product software to perform the upgrade on the endpoint.

If you plan to generate custom installation packages, you must also install the version of Endpoint Upgrade Assistant Package Creator that matches your other Endpoint Upgrade Assistant components. The correct version of Package Creator is bundled with the Endpoint Upgrade Assistant product extension and the Upgrade Automation installation package that is deployed to endpoints during upgrades.

  1. In ePO - On-prem, click Software → Extensions.

  2. Select Endpoint Upgrade Assistant from the list, then note the version number.

  3. Click Menu → Software → Software Catalog (Software Manager on version 5.9.x), then:

    1. From the Category list, click Utilities & Connectors.

    2. In the right pane, expand Endpoint Upgrade Assistant and Package Creator.

    3. Check-in EUA extension.

    4. (Optional) Search for Endpoint Upgrade Assistant Package Creator and download to the same version as Endpoint Upgrade Assistant, if needed. Required only to generate custom installation packages.

    You can also log on to the Trellix Product Downloads site to search for new versions, using the grant number and email address associated with your product subscription.
