1. A method, comprising: parsing, via an application migration module, source code for a transactions on Unix extended for distributed operation application; identifying at least one application service routine that each specifies an associated transactions on Unix extended for distributed operation service within the parsed source code, where at least one identified application service routine comprises at least one associated application-to-transaction manager (ATMI) application programming interface (API) routine; generating stub code comprising an invocation call for an associated customer information control system service for each application service routine identified within the source code; and creating a customer information control system environment executable based upon the source code, the stub code, glue code, and a migration library comprising, for each associated ATMI API routine, a mapping routine that processes data format differences between each ATMI API routine and at least one associated customer information control system API routine.
