CSP/VaGen to COBOL Conversion
The conversion of old, obsolete and/or unsupported programming languages to IBM's strategic COBOL for OS/390 is an important step to enabling an organization to take advantage of the latest in technological advances. Continued compatibility with current versions of strategic OS/390 and z/OS software and the benefits of the increased functionality of the new compiler provide the incentive to effect this conversion as quickly and accurately as possible.
PRINCE Software offers extensive experience and a proven track record in the planning and execution of operating system, program language and data conversions. Our staff is comprised of information technology professionals, specifically trained and experienced in the disciplines required for the successful migration process. Because of our extensive experience, we are able to provide significant flexibility in adapting basic migration techniques to support each client's unique application environment.
A primary factor in our success in the conversion arena is our ability to develop and implement automated tools to assist in the conversion effort. From a fully automated COBOL conversion product to a programmer interactive workbench used for Y2K remediation, PRINCE has relied heavily on automation to assure an accurate, consistent and cost-effective conversion.
Project DescriptionThe primary objective of the migration is to convert the source language of the selected programs to COBOL, while maintaining the same application functionality. In this case, the source language may be any language that produces External Source Format (ESF) files, e.g., CSP, VaGen, etc.
To achieve the goals of increased standardization and continuing compatibility with the latest versions of strategic software, PRINCE Software will develop an approach that will:
To this end, PRINCE Software is in the unique position to provide the necessary elements to assure the successful completion of the application upgrade:
In selecting PRINCE Software to assist in the migration effort, you can be assured that the upgrade will be performed in a professional, timely and cost-effective manner.
Migration ProcessIn general, we recommended that the workload be divided into conversion groups of 50-100 applications. The first group will serve as a pilot project to verify the conversion process, options and results. Each conversion group will be processed as follows:
Testing consists primarily of a regression test to assure that the programs continue to execute and produce the same results as before the conversion. Testing results should indicate that all the screen layouts, and database output should remain identical between the existing and converted systems.
To achieve the goal of minimizing the risks involved in the migration process, it is important that careful consideration be given to the test-bed selected for this testing. Client personnel must identify test files that contain representative business data. The test-bed should be of sufficient size to test the performance, as well as the accuracy of the converted programs.
