Some specific aspects of the source environment need to be implemented in the parameterized parts of the Conversion Migration Transformation tools in order to optimize the automated translation and procedures. The different actors of the project organization must become familiar with the tools and procedures they will use. The "pilot" batch of programs serves this purpose. This prototype set of programs will consist of programs that are representative of the technical differences within the entire inventory. Conversion Migration uses an extensive library of specialized software (analyzers, generators, translators, simulation tools) and advanced programming & testing methods (quality measurement, source compare, database and file comparison tools). We make sure that the migrated programs will produce output functionally equivalent to that produced by the original programs. Conversion Migration offers an integrated approach to convert existing systems to new environments. Using special software and management techniques, it decreases the time needed for JCL, PROGRAM, SCREEN, REPORT, FILE and DATABASE conversion. The transformation process helps to achieve the needed changes in programming languages, program structures, operating systems, data communications and data management, while preserving processing logic.
