Legacy application modernisation is the work of bringing an ageing system forward without a full replacement: updating the stack it runs on, separating the parts that can be rebuilt, and keeping it running throughout, because the business still depends on it.
Let's TalkEffort spent working around age and fragility goes back into the work the software is supposed to support.
Modernisation happens in stages around a system people still depend on, rather than through a switch-off and a gap.
Bringing the stack up to date closes the exposure that comes with unsupported components.
Current technology means a wider pool of people can maintain it, instead of depending on whoever knows the original.
This is one part of our custom web application development work. Engagements rarely stay in one box: a platform rollout turns into something custom, and both then need looking after. That is why our software development and implementation practice treats implementation, custom development, and ongoing support as one continuous piece of work rather than three separate vendors.
