Netvault Exchange Plug in

Hi guys

Our set up is Netvault 11.4.0.22 and Exchange Plug in 11.3.0.2

Is it possible to upgrade the Exchange Plug in only to latest release? If so, how do you do this? I need to update Exchange 2016 to latest CU but I am limited I believe by Netvault to a maximum of CU 13, anyone know if I can upgrade beyond this CU?

best wishes
