Migration & Modernization Strategies
Opening up the mainframe with Service Oriented Architecture (SOA) is not the only possible approach. Here are some links on other strategies for migration and/or modernization of Legacy Systems.

| A Description of the Dell Enterprise CoBOL Compiler | A description of the Dell Enterprise CoBOL compiler for x86. It also has impressive database precompiler support for embedded SQL, including IBM DB2 ad Oracle Pro*Cobol. It can be deployed on both Linux and Windows platforms. |
| Bull HN Services Converts Database to Open Source and Eliminates License Fees | Bull Services performs a database conversion from IDS/II to open source PostgreSQL, eliminating recurring database license fees, performing on time and under budget, for the Oklahoma Employment Security Commission (OESC). This paper explains how it was done. |
| French Social Security CNAF Modernizes CoBOL with Novascale 9012 | CNAF, the French version of Social Security, "right-sizes" its CoBOL applications onto super-powered Intel Itanium based Novascale hardware. All databases have been converted to PostgreSQL and run the daily production load. The legacy COBOL applications continue to execute on the mainframe and directly access PostgreSQL on the Intel Linux platforms. One billion SQL statements are executed daily! |
| Modernization Using Transposition Techniques | Transposition is a modernization technique that refactors code, migrates logic, and translates the code’s language. Transposition also replaces legacy components with new ones and re-architects the application structure to the new platform. Gizmox Transposition has a suite of tools to perform transposition to move VB6 applications to ASP, VB for .NET, or C# for .NET, Powerbuilder applications to .NET and HTML5, and non-.NET applications to .NET. |
| Moving CoBOL from Mainframe to X86 | A case study of a successful migration / re-hosting from the mainframe to x86 super-server, using Dell Enterprise CoBOL. |
| Re-Hosting CoBOL Transaction Based Systems using Dell Re-Hosting Software | As an adjunct to Dell Enterprise CoBOL for x86, Dell also offers re-hosting software for transaction-based systems and multiple databases. This paper presents some of their capabilities, backed up by more than 30 case studies of successful re-hosting projects. |
| The Risks Inherent in Complete Application Rewrites | Presents a list of links to several references that are often quoted and used to explain the difficulties and risks in writing applications from the ground up. They also help in giving a big picture view of how the IT industry faces risks when it comes to fulfilling business requirements. Software modernizaton and migration experts, such as Gizmox Transposition, use these references to also explain the risks and probable success factors in rewriting applications. |
