An international insurance company needed to convert from their legacy IDMS and VSAM databases to DB2 on a z/OS platform using COBOL. An assessment and successful proof of concept was performed in late 2011. The results proved the performance of the DB2 database and quality of the converted application code. The conversion of over 17,500 components and 4.5 million lines of code is currently in progress. Production cut-over is scheduled for September.
