IBM i Modernisation
Go beyond the green screen by modernising your IBM i Applications

Take advantage of modern technology
While RPG or COBOL may remain the engine room of your enterprise, proving their resilience and reliability through their years, as procedure and technology changes, some of this code may require maintenance or enhancement, new interfaces or integrations may be required, or the addition of web or mobile applications needed.
We can further engineer your enterprise, built upon, around or enhanced through proven methodology using robust open-source, and new technologies.


Delivering a web-based GUI for 5250 green screens
We can help you bring your existing 5250 green screen applications to the web by modernising existing RPG and COBOL applications to deliver a modern web-based GUI.
At the same time, our team of IBM i developers can customise your emulated screens to include advanced functionality.
Modernise IBM i applications with PHP
PHP is the most popular web language on the planet, and with our IBM i PHP team we can develop new functionality for your application, making your applications web-enabled, extending your applications on mobile and providing better integrations with modern APIs and open source.
We can even rewrite existing applications which can then be combined with your 5250 green screen functions to run in a single browser session with no tabbing, launching or navigating required.


Transforming and modernising application
For any organisation, of any size, access to modern, user-friendly applications is essential. Modernising an IBM i application so it is user-friendly, browser-based and mobile-enabled, can be a daunting prospect.
We can either deliver those modernisation projects on your behalf, or provide you with the GUI, web and mobile enablement tools you need to do the job yourself (with full training and ongoing support) through our partnership with Fresche Solutions.
Create new applications and modern GUIs
Enable the delivery of your IT strategy with direct access to developers skilled in Java, PHP and other languages.
Whether you need real-time mobile apps or easy-to-use GUIs to replace green screens, we have the expertise to support you.

Use Cases
Modernise your IBM i applications
When you need to ensure your AS400/iSeries/IBM i applications are relevant for today’s users, our team has got you covered.
If you have a very specific use case, don’t hesitate to get in touch and we can discuss your specific requirements.
IBM i applications that were designed and built with a green screen first approach, often don’t meet the experience that modern users are accustomed to. We can help take your IBM i applications and modernise them with familiar UI components, and experiences that today’s users are familiar with.
Our application specialists can use a number of approaches to transform your IBM i applications into fully web-enabled, cross-device compatible applications, adding additional functionality, a better user experience, and opening them up to better, modern integrations via API.
If you just need access to the right software tools for IBM i modernisation, but don’t actually need someone to deliver the project on your behalf, we can provide training, advice and support to transform your green screen applications.
