What function it will do under this---> this will auto upgrade feature for the group. CLients which are running old version will upgrade to the one mentioned over there SEP 12.1 .

That option is used to assign packages to Groups

if your client is running any older version ..u can assign a new version to a particular group so that they upgrade the software automatically..

With the Help of Install Packages, you will be able to deploy the SEP agent on to your network either Remotely or manually
