There have been a number of enhancements released or due that will be for 100c only as reviewed in the Sage 100 Partner Advisory Council meetings, so there will soon be a clear differentiation. It was also definitively stated in the BPAC meeting that Sage wants all current customers on the C line versions. They stop short of forcing 100 customers to upgrade due to Stephen Kelly's proclamation about no forced migrations, but I am guessing the relative annual increases in maintenance/subscriptions plus the new enhancements only for C will make the decision obvious for customers. I was surprised to find out that the percentage of customers who have already migrated was less than 60%, so Sage has some convincing to do. Of our customers current on maintenance, we only have 6 remaining on 100. I need to document the new enhancements for those hold outs, so I can share that when I complete it.
