Many of today’s mainframe applications that were developed in SAG Natural and Adabas are still mission critical and continue to deliver significant benefits to the organizations that use and rely upon them. Nevertheless, the Total Cost of Ownership and technological risk associated with these applications have now escalated to unsustainable levels. CodeTurn for Natural to COBOL migrations provides an opportunity to liberate these valuable and reliable business systems from their dependency upon non-strategic, legacy technologies and enable them to be integrated with state of the art components. Our CodeTurn supports COBOL, Java and C# as target languages.
CodeTurn for Natural to COBOL migrations takes any application developed in Natural and automatically converts it into a fully identical application, designed to run within an alternative environment on the same platform, or a different platform altogether. The new application is completely free of dependencies on Natural technology and, instead, uses modern and industry standard development tools such as Java, .NET and COBOL to allow flexible application integration and extension.
The Astadia migration process utilizes Natural’s SYSTRANS output format, in order to migrate the Natural artifacts. This approach largely isolates the Natural to COBOL conversion from the underlying system, therefore every Natural platform is supported.
A converted application can run on either Open Systems with Linux, Unix or Windows, in the Cloud, or on IBM Mainframe. The chosen target platform is simply selected as a configuration option during the conversion process.
When the target platform is LUW, additional Astadia tools handle the transformation of other source types, such as JCL, Assembler and COBOL programs, thus ensuring that the entire application runs on the new platform.
End-users can connect to the application with either a web‑browser or their current Terminal Emulator.
The Terminal Emulator can optionally be retained for connection to the migration application, which enables the switch-over to be 100% transparent to end-users.
Many Natural mainframe applications are enhanced or integrated through third party screen-scraping technology. Astadia's Natural to COBOL conversions provide byte-to-byte compatibility with the existing mainframe protocols. Therefore, screen-scrapers remain compatible, even on Open Systems.
The table below summarizes how all the Natural object types are converted into their COBOL counterparts.
After migration, all COBOL code is maintained using standard development tools on the chosen platform. The converted Predefined maps can be maintained using our MapEdit WYSIWYG editor to further facilitate application integration and modernization.
Natural is recognized as a rich and powerful development environment. The Astadia Natural to COBOL migration tools provide support for advanced Natural language features, including:
The Adabas database and all its data are migrated automatically to a relational database (RDBMS).
