Rational’s Application Transformation Solutions Migrate from older languages and expensive tools to modern development platforms, languages, databases and tools Operating costs were reduced 55 percent by migrating from the VAGen legacy application to Java. “The migration to EGL combines the best of both worlds: The stability of IBM System z and the flexibility of Java.” Massive cost savings are also included! — Frank Landewee, project manager, Atos Origin GmbH, Essen SAG Natural/Adabas CA Ideal/Datacom CA Cool:Gen RPG COBOL Green screen text UI’s (3270 or 5250) VA Generator GUI’s ,[object Object],[object Object],[object Object],[object Object],Conversion Tooling EGL Testing, Remediation, Deployment System z – CICS System z – Linux 1 System z – Batch System z – WAS 2 System z – VSE IBM i - WAS IBM i - Native AIX HP - UX Solaris Linux Windows 1 Eligible to run on IFL 2 Eligible to run on zIIP and zAAP WEB 2.0
