1. A method, the method comprising: presenting, using a user interface, a transactional workflow driver (TWD) to visualize a representation of a legacy application; identifying, using the TWD, from the visual representation of the legacy application, legacy application processing components and legacy application execution patterns; presenting, using the TWD, a visual representation of extender processing components; identifying, using the TWD, by comparing the legacy application processing components with a target application, one or more extender processing components from the visual representation of the extender processing components that extend the legacy application to generate: the desired target application; and extender execution patterns defined by the extender processing components; selecting the one or more extender processing components from a extender processing components repository; ordering into an execution sequence the one or more extender processing components and the legacy application execution patterns; generating and storing, in a memory coupled to a processor, a target application processing vector that represents the ordering of the legacy application execution patterns with the extender execution patterns; and executing, using the processor, the target application processing vector to perform features defined by the target execution pattern.
