Legacy transformation
Protect the business while modernizing the technology.
Modernization does not always mean replacement. Choosing correctly is most of the value.
A legacy system that works is an asset with a maintenance problem, not a liability to be removed on principle. The expensive mistake is treating every ageing platform as a replacement candidate — and the equally expensive mistake is leaving one in place when it has become the constraint on everything around it. The judgement about which is which is the work.
Capability
Three approaches, chosen per system
Most estates need all three at once, applied to different platforms.
Extend
Enhance and support what works. Where a platform is stable and still fits the business, the right investment is keeping it healthy and adding capability at the edges.
Integrate
Open the platform through APIs without disturbing it. New capability is built around the system rather than inside it, and the core stays stable while the surface becomes accessible.
Transform
Move selected workloads, deliberately. Where a platform genuinely constrains the business, we move it — one workload at a time, with the runtime behaviour proven at each step.
Outcomes
Where our evidence comes from
- Migration of a global bank’s relationship-management users from a legacy mainframe platform onto a Java portal
- Migration of a 21-application reporting estate across application server generations
- Long-running support of WebSphere, WebLogic and JBoss estates on Linux, AIX and Windows
The question is not whether a system is old. It is whether it is the thing standing between the business and its next capability.
Bring us a difficult technology problem. We will help define the practical path to solving it.
