Run the InstallShield Wizard to upgrade your ePO - On-prem server.

Tip

Monitor the upgrade process. You might need to restart your system.

  1. Log on to the system using an account with local administrator permissions and find the Setup.exe file.

    The executable is located in the folder where it was extracted.

    Important

    If you try to run Setup.exe before extracting the contents of the .zip file, the installation fails.

  2. To start the ePO - On-prem InstallShield wizard, right-click the Setup.exe file, and select Run as Administrator.

  3. In the Welcome dialog box of the installation wizard, click Next.

    A warning message might appear listing products from your previous version of ePO - On-prem that are no longer supported with this version of the software. These products are not migrated to the new ePO - On-prem repository.

  4. To install the listed software, click Next.

  5. In the Database Information step:

    1. Confirm that the automatically selected Database Server and Database Name are correct.

    2. Specify the type of credentials to use from the lists.

  6. Specify which type of Database Server Credentials to use, then click Next.

    • Windows authentication — From the Domain menu, select the domain of the user account you're going to use to access the SQL Server. Type the User name and Password. If you are using a previously installed SQL Server, make sure that your user account has access.

    • SQL authentication — Type the User name and Password for your SQL Server. Make sure that credentials you provide represent an existing user on the SQL Server with appropriate rights.

      Tip

      The Domain menu is grayed out when using SQL authentication.

    The ePO - On-prem Pre-Installation Auditor runs, analyzing your ePO - On-prem environment to make sure it meets all requirements.

  7. In the Administrator Information step:

    1. For the Username, replace the default admin if necessary, and type your primary Administrator account user name.

    2. For the Password, type your primary Administrator account password.

    3. For the Server recovery password, type a passphrase to encrypt Disaster Recovery Snapshot records.

      The passphrase includes 14–200 characters, must not contain leading or trailing backslashes (\), spaces, double quotation marks ("), or characters below ASCII 32 or above ASCII 65535.

      Note

      Keep a record of this password. If you ever want to restore ePO - On-prem from a Disaster Recovery snapshot, you need this password to decrypt the Disaster Recovery Snapshot records.

    4. Click Next.

  8. In the Type License Key step, click Next.

    Your existing license key is automatically populated in the field and the Product Compatibility Check runs.

  9. Accept the Trellix End User License Agreement and click OK.

  10. In the Ready to Install the Program dialog box, decide if you want to send anonymous usage information to Trellix, then click Install.

  11. When the upgrade is complete, click Next, click Finish, then optionally select to restart the server.

    Note

    During the upgrade process, if your ePO - On-prem database is large, the process might take a long time and this message appears: Your ePO - On-prem database has too many events. Your upgrade might take a long time. For information about removing old events, see KB68961.

  12. In the InstallShield Wizard Completed dialog box, click Finish to complete the installation.

    If you want, click Yes, I want to start Trellix ePolicy Orchestrator-On-prem now.

Your ePO - On-prem software is now updated. Double-click the Trellix icon on your desktop to start using your ePO - On-prem server, or browse to the server (https://<servername>:<port>).
