One of the Major issues we faced with Adobe campaign is the ID resequencing issue. We only have 4 billion id's available. I have heard that the PrimaryKey ID sequencing for the Nms Tables in the Adobe Campaign V7 has 64 bit sequencing. It will surely workout for new clients installing V7, but what about legacy clients (clients upgrading from V6.1.1 to V7)? Will the tables be changed to 64 bit?
