Enterprise vs Sugar Sell, Serve, Market Etc

We are current SugarCRM cloud users and are on Enterprise.

As SugarCRM has now re-branded it's offerings to Sugar Sell, Serve, Market etc I was wondering if there's a resource that outlines what of these functions are included in "Enterprise".  And more importantly, what is not and is there an ability to add or move to these modules easily and cost effectively.
