Hi web1b, you just need to create a new framepkg package from ePO with the new McAfee Agent version.
So you have to go to System Tree, click on System Tree Actions->New systems->Create and download agent installation package->select the McAfee Agent version you want to use and after clicking on OK you will be able to download the new package
The Package file which you have its McAfee standalone Agent package which will comes with every VSE installation package. You can download ePO frame package file from ePO installation directory or steps suggested by Laszlo G.
Frame Package file location :
...\Program Files\McAfee\ePolicy Orchestrator\DB\Software\Current\EPOAGENT3000\Install\0409
