Microsoft heard our feedback guys and took them very seriously regarding the portability of the solutions created in the development environments. You can now take all the lists, libraries, site assets, data and forms, package them up all into one file and easily deploy them onto different environments!
Now, the question is “What about InfoPath forms?”
In InfoPath 2010, all the links you have to external data are now relative, so when you move that form to different environments, those links will continue to work.. I really appreciate this!
