It's interesting that no one from Symantec has answered this question yet as it would seem to be pretty straightforward. I had a chat session with a license rep trying to get an answer to the same question and ended up more confused than when we started. I believe there’s new functionality built into the Advanced Server part of DCS:AS and if you want that then you need to buy it as the old license under CSP will not cover it. My organization ended up purchasing the new product but again, I’m not sure about all of this because I could not get a clear answer to a very simple question and we did not want to risk any type of license violation – very frustrating.
