WOW 3 call outs in a row You got my attention.
It actually depends on the title. If DSD had already had the title then it is called an ""DSD Replacement"" in which you just had to pay maintenance. Now if it was a new title to DSD then there was an associated jump fee..
DSD Replacements: These ES titles will be replaced by DSD's version of the product and upgraded to version 4.40 right away. We will make these products available to users that own prior versions of the Extended Solution for the price of a Maintenance Plan, and there will be no additional fee to upgrade to version 4.40.
4.40 Jump Fee Titles: These ES titles will require some redevelopment effort to upgrade to the Business Framework for version 4.40. We will make these products available to users that own prior versions of the Extended Solution for the price of a Maintenance Plan plus a one-time ""Jump"" fee to receive the 4.40 version of the product. These Extended Solutions titles will only be upgraded upon request. Because of the substantial amount of time researching the jump fee price, only those titles having 5 or more end-users will have jump fees shown in our ES catalog. All other titles' jump fees will be made available in a timely way, on request.
