z/OS & z/VSE Mainframe Migrations

Migrating from z/OS and z/VSE Mainframes

For many years, the IBM Mainframe has represented one of the most powerful and stable platforms on which to run the large scale data processing applications used within the global banking, insurance, telecoms, aviation and logistics industries, as well as government services including health, tax, police records and so on. Nevertheless, the improved stability and scalability offered by today’s server and PC technology now represents a viable and more cost effective alternative to the mainframe for many organizations. Astadia’s automated IBM migration solution provides an opportunity to take advantage of these new possibilities.

Solution Highlights

Astadia’ z/OS and z/VSE mainframe migrations is a versatile solution to replace the entire mainframe platform, together with all the core applications that reside on it, hereby effectively eliminating any dependency on costly mainframe technologies.

This is just one of many possible mainframe migration and modernization paths. Other migration scenarios may be where the mainframe platform is retained, but certain key mainframe technologies are replaced with more modern and flexible variants. Here, too, Astadia provides solutions for mainframe technology replacement.

Native Technologies / No Emulation

After the migration,  organizations will be able to provide their core applications with new capabilities, while granting access to exciting opportunities, such as the use of Cloud, DevOps, CI/CD.

By doing this, it is ensured that migrated applications use technologies that are widely recognized and accepted as native on the chosen target platform, instead of choosing to emulate the source platform technologies on another platform.

Whenever the functional equivalence promise requires introducing components into the migrated application that could be perceived as non-native on the target platform, a clear modernization path is offered to eliminate these components for good.

Target Technologies

Astadia's migration solution offers multiple choices when it comes to mapping the source system technologies to their alternative target technologies:

User Interface Modernization

Our CodeTurn tool enables the transformation of many legacy character-based user interfaces, including CICS BMS, Natural and IDMS OLM maps, into modern, open Java or .NET based front-ends that can be maintained using standard development tools like Eclipse and Visual Studio.

When choosing this option, after migration developers can  enhance converted screens with graphical components such as drop-down fields, checkboxes and data lists.

Automated Testing

A key factor of successful migration projects is making sure that the migrated system is ready for production. At Astadia, this is done through extensive and repeated testing cycles.

DataMatch and TestMatch are the core of our automated testing offering for mainframe migration projects. They were built to reduce the time and effort needed to complete this crucial testing phase:

• TestMatch eliminates the need to manually create test scenarios for the complete application
• DataMatch enables quasi automatic testing of batch jobs
• Both limit the end-user involvement in the project for acceptance testing.
