1. MPE to HP-UX (and Linux) a Case Study

2. Rick Gilligan zSr. Software Specialist at CASE since 1980 zTools Developer from 1980-1983 zArchitect and Product Manager for ABLE from 1983-2001 zMigration Manager for MPE to HP-UX Project 2001-2007

3. ABLE - the Asset-Based Lending Environment zInitial design started in 1983 zRan exclusively on MPE until 2002 zFirst production use on HP-UX in October 2007

4. Goals zMinimize impact on client operations zMinimize cost of migration zMinimize distractions to ABLE developers zEffectively manage the time available for conversion

5. Risks zHP COBOL support by non-HP vendors either minimal or buggy (still in development and shake-out) zScreenJet converter still in development

6. Software Tools zHP COBOL/II zVPlus zSPL/Splash! zTurboIMAGE/3000 zQedit for MPE zSuprtool for MPE zInternally developed tools in Splash! and COBOL

7. User Interface zVplus using terminals (historically) and Reflection terminal emulator yMaintenance functions yReport and Processing function selection zBatch reporting and processing producing HP PCL5-formatted spooled output and RightFAX zLimited intranet/Internet HTML output selected from HTML forms (Apache 1.3)

8. Migration Target zOriginal: HP-UX on PA-RISC zFinal: HP-UX on Itanium zCaveat: ALL tools to also support Linux and Windows zCaveat: FEWEST third party tools zAll reporting and processing functions web-based with PDF output zNo spooler or batch job support

9. Third Party Migration Tools zACUCOBOL-GT, Acubench and AcuConnect Thin Client ybest HP COBOL support, including macros ylower run time costs than MF zEloquence yTurboIMAGE plus more zScreenJet yVplus emulation

10. Open Source Migration Tools zJavascript zGnu bash zGnuPG zApache 2.0 zOpenSSL

11. Internally Developed Tools zPDF output directly in COBOL zauto font scaling zline drawing zshading zlogo images zfont color, style

12. Migration Process zMigration occurred first on MPE - remove MPE- specific code zStart with frozen version of ABLE zCOBOL dialect converter that migrates code to ACUCOBOL runs nightly zParallel development of enhancements to ABLE product on MPE zRetrofit four years of enhancements to MPE product to HP-UX product
