Deploy Trellix products that cannot be upgraded using Endpoint Upgrade Assistant

Because some Trellix products cannot be upgraded using Endpoint Upgrade Assistant, you need to upgrade them using another deployment method like deployment tasks in ePO - On-prem.

Note

For the Intel architectures, you can directly upgrade to version 26.x from version 10.7.0 (November 2022) or later. For the ARM architectures, the upgrades are not supported and upgrade section is not applicable, refer 000014791 for details.

You can tag endpoints that require the same solution, then deploy products using a deployment task in ePO - On-prem.

Exporting the analysis details allows you to search, sort, and filter the information more readily; for example, to identify endpoints that need client properties updated (which requires refreshing the ePO - On-prem database).

You can also view endpoints that require specific products and versions in the ePO - On-prem System Tree and link to technical articles, when available.

Task

  1. In ePO - On-prem, select Menu → Software → Endpoint Upgrade Assistant .

  2. Analyze upgrade requirements for your environment.

    1. Select Trellix Endpoint Security 26.x as the version to upgrade to.

    2. Select the endpoints to analyze. The time required to analyze your selection depends on the size of the ePO - On-prem database and the number of endpoints selected.

    3. Click Analyze Environment.

    When the analysis is done, you can view it in the Environment Overview chart.

  3. To see endpoints that you need to upgrade using ePO - On-prem, check Require product upgrades on the Overview tab. Endpoints with similar issues are grouped, so that you can tag them. Each time you tag a group of endpoints, Endpoint Upgrade Assistant creates a tag called UA_<timestamp> in the Trellix ePO - On-prem Tag Catalog.

  4. Click More Info to display the steps required to complete each manual upgrade, including the product versions and number of restarts required.

  5. (Optional) Click Product versions to display product details for the endpoints.

  6. In ePO - On-prem, create a deployment task to deploy the required client software to a group of endpoints, selecting the tag that you created in step 2.

  7. When the required manual upgrades are complete, click Re-Analyze Environment.

    Endpoints that no longer require manual tasks are moved to the Ready for Upgrade Automation table.

  8. Repeat these steps until no endpoints require manual product upgrades.

Results

Once endpoints are ready to upgrade, you can deploy Trellix ENS 26.x and other required software to endpoints.
