I have had this questions a few times this week so wanted to share the answers with everyone.
Scenario: You have built all your maps on SmartConnect v35 and have installed the production server with GP10 and the new SmartConnect v48. What is the best way to move the maps from one server to the other.
Answer: The best option is to export the maps from the development environment and import them into the production environment. BUT – you must first upgrade the developmentenvironment to the latest version of SmartConnect (48). Changes in v48 have meant that the exported XML is not interchangeable between v 35 and v48. So make sure that your two SmartConnect installs are the same version before doing any of your exporting and importing.
