System migration is necessary when the current technologies become obsolete, and more efficient platforms become available. The client required to adopt a new platform when their legacy system can no longer handle evolving business needs.

 The project dealt with S/390 to AS/400 and iSeries.

Client:

A large statewide insurance provider

Project Definition:

• Implementation of medical claim format upgrade – simultaneous with platform conversion effort

Primary Project Components:

• Configuration of the new environment, including all databases and system facilities
• System analysis and development of job and functional flowcharts
• Development, testing and implementation
• Project management
• Post-implementation production support

Project Complexities/Deliverable:

• Meet the goals of an aggressive project timeline
• Convert large volumes of COBOL source code, IBM and other utilities from S/390 to AS/400
• Develop workaround solutions where original source code was not available
• Definition and configuration of the entire CICS environment (PPT, FCT tables, etc.)
• Full database conversion in a 48 hour window - transparent to the production environment
