AI summary

A method and apparatus for migration of application source code may include parsing the source code and generating a first output, dynamically analyzing the source code to produce a second output wherein the second output comprises runtime metadata associated with the application, converting, using the runtime metadata, the source code of the application in an original language to a destination language on the second platform and a data source in an assigned format to a destination format. The method may include simulating memory to execute the source code by simulating a dynamic memory array, executing the source code within the dynamic memory array, detecting and resolving parameters of the source code by monitoring execution of the source code, and storing the detected and resolved parameters of the source code in a metadata register.
