SEP SBE to SEP EE

Hi,

I hope this is being posted in the correct forum, if not please move.

I am upgrading our SEP SBE 12.1.5 to SEP EE 12.1.6. My question is will the clients automatically update to the latest verstion (12.1.6) or will I need to manually push the update from Install Packages > Upgrade Clients With Package.

If I need to manually push this update what is the best way to do this since the packages are 32 and 64 bit? Our groups are sorted by Servers / desktop not OS type.

Thanks.
