  1. AS/400 Migration Wei Lan wlan@microsoft.com Consultant Microsoft Technology Center

  2. Migration Drivers • High cost of operations, upgrades • High price-performance of AS/400 ecosystem • Lack of flexibility to meet business needs • Long time-to-market for new products – slow to change • Poor Supportability Issues with the AS/400 or AS/400 applications, that are common to a lot of AS/400 customers

  3. Migration.. But How?

  4. Migration Strategies

  5. Re-platform Applications Wrap or Front-end Applications Redesign – New Functionality Migration Strategies • Redesign application for Windows platform • Examples • Rewrite CICS application in .NET • Convert DB2 app to SQL Server Risks Benefits • Move applications from mainframe environment to Windows environment without change • Examples • Recompile source, use CICS emulator • ISV app migration • Leave application on mainframe, add front-end on mainframe or Windows to provide additional functionality or UI • Examples • IIS talking to DB2 on mainframe • Three tier architecture Faster

  6. New Design, New ApplicationBig Bet, Big Bang !! • Risks inherent in any large scale new software development project. Replace mainframe application with a new native .NET application. Either individual applications or whole environment. Advantages: Caveats: Strategy Definition • Design for improvement in performance. • Takes advantage of .NET functionality. • Clean-room advantages – all code can be fully documented, latest devices can be supported, etc. • Modern current design versus layers of modifications over many years of evolution.

  7. Case Study - Countrywide Financial Corporation

  8. Background Countrywide Financial: leading provider of consumer and business financial services in U.S.

  9. Background • Company Profile: A leading provider of consumer and business financial services in U.S. • Its AS/400 Tax Service System tracking Countrywide’s six million mortgage loans – a portfolio that’s growing by 100,000 loans every month. • Countrywide was close to using all available resources on the AS/400. • The ONLY choice was to purchase another AS/400 solution for another US$ 2.3 million. But…

  10. Challenge • Could not know whether it would be buying enough power/resources for the next few years. Company may quickly outgrow the additional system. • Old problems with AS/400 still exist: • 8 hour nightly window for batch jobs • Still “Green screen” ? “We want a solution that could scale with the increase in Coutrywide’s portfolio growth and also maximize the ROI on our investment .” - Paramjit Chumber, Senior V.P. and CIO, Countrywide Financial

  11. Solution • Work with Microsoft Consulting Service (MCS) to redesign the whole system to distributed Windows platform with .NET Framework • Migrate and create 15 new Tax service applications within 20 months App Farm Enterprise Service Web Farm ASP.NET Data Sources SQL Server 64bit

  12. Benefits • Save US$ 1.7 million over the cost of expanded AS/400 solution: US$1.2million (savings in hardware and software) + US$500,000 (annual savings of maintenance fees) • Productivity increases 43% measured by the number of loans it process -> $2.5 million increased revenues • Plan its infrastructure investments more effectively, buying only as much as need now, and scaling out with additional servers only as needs require.

  13. Case Study - Presidential Life Insurance

  14. Background • Company Profile: Founded in 1965 and located in New York, Presidential Life Insurance is a leading provider of annuities and life insurance products to financial service professionals in U.S. • The legacy AS/400 system that supports the life insurance operations comprises over 160 screens and over 650 COBOL programs.

  15. Challenge • AS/400 are expensive machines to purchase and maintain – often an order of magnitude more than similarly powered PC configurations. • Independent Software Vendors (ISVs) are no longer developing add-on tools for the platform. • The software on the AS/400 was perceived to be falling behind that available on other platforms in terms of usability and flexibility of data reporting.

  16. Solution • Migrate to Fujitsu NetKicks, NetCOBOL® for .NET on Windows Server 2003. • Started the implementation of their migration plan for all systems in the summer, 2004 and complete at March, 2005

  17. Fujitsu CICS & COBOL Tools Transaction Manager: CICS Programming Language: COBOL Screens: BMS NetKicksTM • A BMS map to ASP.NET wizard • An “EXEC CICS” program translator wizard • A NetKicks “Executive” runtime • A Property Manager for PCT, MCT and FCT NetCOBOL®for .NET • Fully integrated with Visual Studio .NET • Access to the .NET Framework • Verifiable COBOL • Interoperability with other .NET Languages Transaction Manager:NetKicks(“Executive” Runtime) Programming Language: NetCOBOL for .NET Screens: ASP.NET

  18. Integrate Analyze Report Benefits Less Migration Time Faster Building New Applications with Visual Studio.NET SQL Server Reporting Service with Embedded in Business Intelligence functions. • Data presentation and distribution • Data access for the masses • Data enrichment, with business logic, hierarchical views • Data discovery via data mining • Data acquisition from source systems and integration • Data transformation and synthesis

  19. BMS Converted to Web Forms and enhance with GUI controls
