When migrating we can check it in many different ways, after you pushed the installation via the ClientRemote Tool, on the server side you will see it on the clients Page. on the workstation side, you will see the new shield icon on the system tray with green dot.
As per procedure, when we install SEP over SAV, it should automatically uninstall SAV then install SEP, (sometimes it needs restart)
but in this case, please investigate your SEP _inst.Log if you are having problems on a particular workstation.
