Insurance company in Japan
Application migration from ADABAS to DB2
The company is one of the biggest insurance companies in Japan and is ranked 12 in Fortune 500. About 25% of the Japanese families are insured by this company.
Following the migration to IBM mainframe the company decided to migrate its COBOL / Natural / ADABAS applications to COBOL / DB2. The goal of the project was to reduce operational cost and to move to standard infrastructure and software products.
Customer requirements were:
Elimination of all SAG products
100% preservation of business logic and screens
Transparency for end users and ongoing system operations
Preservation of performance in both on-line and batch
Minimum changes to the COBOL programs (if at all)
Ensuring business continuation throughout the project
450 Natural Entities
25,000 COBOL programs (Bach and CICS)
2000 Assembler routines
40,000 Sequential files 40,000
860 DB2 tables 860
370 ADABAS files
2700 Interfaces to external systems
50,000 Number of users
Project Methodology and Timeline
The migration was conducted in 3 phases:
Phase 1 - preparation of the new technological infrastructure, tools customization & migration of one small subsystem.
Phase 2 – conversion of a subset of applications.
Phase 3 – conversion of the remainder of the applications.
The company allocated a dedicated communication line between its mainframe and MOST's off-site center in Tel Aviv.
A testimonial to the success of the project is the ongoing relationship and additional projects, which MOST has conducted (and still is) since this project has been completed. The following summarizes the company's satisfaction:
"A project that came in as planned without any production glitches, MOST exceeded our expectations without fails"…
