Symantec Endpoint protection v12 to 14. Problem updating clients.

We have recently upgraded our endpoint protection from version 12.6 to 14. I have created a package that I can push to all my users but I don't have all the pc's in the list and we have a ton of groups. 

Before we used to update the Endpoint and the clients would automaticly update to the latest version. Is there a way for all the clients to automaticly update to the version 14.

Thanks,
