Application Migration
The essence of software re-engineering is to improve or transform existing software so that it can be understand, controlled, and used anew. The need for software re-engineering has increased greatly, as heritage software systems have become obsolescent in terms of their architecture, the platforms on which they run, and their suitability and stability to support evolution to support changing needs. Software re-engineering is important for recovering and reusing existing software assets, putting high software maintenance costs under control, and establishing a base for future software evolution.

Do you have applications that exhibit the following traits, basically which are ‘technologically’ obsolete but with a high business value?

Poor or no support from Vendor (Unsupported environments and   platforms & Niche market players , non generic Mainframe stack like   IDMS, IMS, Adabas/ Natural , Focus, PL/I
Paucity of skills like RPG/400, Assembly, Focus, IMS, PL/I, Adabas/   Natural & Assembly
Shares the familiar traits of a legacy application such as
Inflexible to change
High maintenance costs
No equivalent package available in the market(Very unique to the   client’s way of doing business or would require extensive   customizations if a package were to be implemented)
No magic bullet available where the tools can ‘transform’ the legacy   code into a neatly structured Java or C# code.

Application Re-engineering in a nutshell
Reverse Engineering to extract the business rules
Forward engineering under J2EE (in Java) or C# (in .NET)
Extensive amount of testing to ensure that the reengineered application   & the current applications behave identically.
Usually involves data migration to either Oracle (for J2EE) or SQL   Server (for .NET)

Benefits of Migrating away from Mainframe to J2EE or .NET
Positioning the applications for the future
Lower operational & maintenance costs
Address Skills shortage issue
