You can also upgrade an appliance in Hyper-V environment by binding the downloaded .iso image as a virtual CD drive.
Note
If you are upgrading a virtual appliance from a Trellix DLP version lesser than 11.0.0, we recommend that you deploy a new virtual appliance. This is due to the changes in the virtual hardware to support DLP Capture.
Open the Hyper-V Manager console installed on the Windows Server.
Press the Windows key and type "Hyper-V Manager" to search applications for Hyper-V Manager or open Hyper-V manager from the Windows Start menu.
Select the server where you installed the virtual appliance.
Right-click the virtual appliance and select Settings.
From Settings, select IDE Controller 1 → DVD Drive, and select Media → Image file.
Browse to the .iso file and click OK.
In the virtual appliance window, click Start from the Actions menu.
From the appliance console menu, select Reboot to restart the system.
Select the full installation mode, which is the default and the recommended option.
Follow the on-screen instructions to reimage the appliance and configure the appliance from the Setup Wizard.
