Upgrade from BEWS 11d to 12.5

Well, when I run the environment check, I get the warning about needing to have Symantec Endpoint protection installed on the server.  I currently have McAfee AV and Mcafee HIPS running on the server.  Do I really need to uninstall McAfee AV and HIPS and install Symantec AV and Endpoint protection for Backup Exec 12.5 to work?
