1. A method performed with a computing system for integrating software applications, the method comprising: identifying at least one enterprise application executable in a first computing environment, the enterprise application compatible with a first version of a network application executable in a second computing environment communicably coupled to the first computing environment so that a first set of functionality of the first version of the network application is exposed through the enterprise application; identifying a second version of the network application executable in the second computing environment, the second version of the network application comprising a second set of functionality at least partially distinct from the first set of functionality; and delivering an integration component from the second computing system to the first computing system over a network, the integration component comprising an application specific, non-reusable and non-modifying add-on component that is uniquely associated with the enterprise application and exposes at least a portion of the second set of functionality of the second version of the network application through the enterprise application, the integration component configured to maintain an execution of the enterprise application without retesting.
