You can create a deployment link in ePO - SaaS to upgrade to Trellix ENS 26.x on your own endpoint, then send it to users so they can upgrade their endpoints. The link downloads and installs the software on each endpoint. You can upgrade from version 10.2.x, 10.5.x, or 10.6.x.
When you use ePO - SaaS to install Trellix ENS, users can initiate the installation on their endpoints when it's convenient.
Note
The installer now automatically detects missing Root or Intermediate certificates on the endpoint before proceeding. This check prevents installation failures caused by incomplete certificate chains.
Before the installation:
Verify that all endpoints meet the minimum requirements (KB82761).
Verify that you're aware of compatibility requirements for other installed products.
On endpoints running Microsoft Windows 10 October 2018 Update or later, verify that the case-sensitivity attribute is disabled for folders in your source and target installation paths and \Windows\System32\drivers.
Verify that endpoint users have permission to access the user temp folder (KB85033).
Verify that the newer Root Certificates have been applied to the endpoints (KB91697).
If you plan to save custom product settings, review your settings, client tasks, and assignments, consolidating them where possible. Remove duplicates and unused objects.
After the installation:
If you saved your custom product settings, verify that settings you configured in the previous version work as expected.
Disable the Windows firewall to avoid conflicts with McAfee Host IPS rules.
Review the policy settings that are new or changed in Trellix ENS 26.x.
