Legacy modernisation: modernise and speed up sorting processes without putting existing systems at risk!


More than just sorting – here’s how to make your data workflows more powerful, flexible and future-proof!

Do you still use COBOL, JCL or operating system-based sorting tools when processing large volumes of data?

These traditional solutions date back to a time when data sets were manageable and systems were largely isolated. Consequently, they are often complex to configure – and their functionality remains limited.

Beyond simple sorting, merging and a few transformations, they quickly reach their limits. Particularly in modern, distributed data landscapes, they can barely keep pace with the dynamics and diversity of today’s data. In short, they fulfil their purpose – but do not evolve in line with your requirements.

The consequence: teams resort to workarounds. They combine multiple tools, add extra process steps and move data around to implement a single workflow. This increases runtime, costs and overall complexity.

It is not just a matter of finding a faster sorting solution. The real challenge lies in modernising existing processes without jeopardising what has been tried and tested.

In concrete terms, this means:

This is where a modern approach comes in: instead of developing everything from scratch, existing workflows are adopted, enhanced and transferred to a flexible, scalable environment.

This also means offloading processing tasks to open systems – without disrupting ongoing operations – whilst simultaneously unlocking additional functionalities.

This is how modernisation is achieved without disruption: not through complete replacement, but through the targeted further development of proven processes. And that is exactly what IRI CoSort enables! Find out here how legacy sorting jobs can be securely transformed and efficiently modernised.

Efficiency meets experience: For more than four decades, our software solutions have been supporting companies in data management and data protection – technologically leading, reliable in productive use and applicable across all industries.

In use since 1978: Numerous well-known companies, service providers, financial institutions and state and federal authorities are among our long-standing customers.

Maximum compatibility: Our software supports both classic mainframe platforms (Fujitsu BS2000/OSD, IBM z/OS, z/VSE, z/Linux) and modern open system environments such as Linux, UNIX derivatives and Windows.
