Like the title states... If we install the network edition and run for a couple months will the existing open source edition be easily upgradeable to the Network Edtition? We like the all in one mail package zimbra offers and we need the outlook connector to work but at the time we think the outlook connector isnt quite where it should be for us to migrate to that yet. (We currently are using XC connect). But we think zimbra is making great progress and will be there soon.
