Consulting / Mainframe modernisation
Move off the mainframe, without a big-bang risk
COBOL, CICS, DB2, IMS and AS/400 systems still run the business, but the people who know them are retiring and the running cost keeps rising. Our architects move them to cloud step by step, with the same business rules and tests at every stage.
Sounds familiar?
- COBOL and RPG experts are retiring and hard to hire
- High MIPS and licence cost every year
- Changes take months and nobody wants to touch the code
- Data is locked in DB2, IMS or VSAM and AI cannot use it
How we do it
Assess
An inventory of programs, jobs, data and links, with the business rules that matter most.
Convert
Code moved to Java, .NET or a cloud native service, with automated tests built from today's outputs.
Test and run in parallel
Old and new run side by side until the numbers match.
Switch over and improve
A planned cut over, then APIs and AI on top of the data.
Typical timeline: A first assessment in 2 to 3 weeks; a first module live in 3 to 6 months; the full move in phases.
Services for this
Questions buyers ask
Do we have to move everything at once?
No. We move one domain at a time and keep the mainframe running until each part is proven.
Will the business rules change?
No. The same rules are kept and checked with tests built from today's outputs.
Which targets do you use?
AWS, Azure, GCP or your own data centre, in Java, .NET or managed services.
Can you also handle AS/400?
Yes, AS/400 (IBM i) with RPG is part of the same practice.
