Legacy Analysis

Legacy software isn’t just old code - it’s a living part of your business. But when documentation is missing, key staff have moved on, and the original architecture has evolved beyond recognition, even basic changes become risky.

Our analysis starts at the ground level. We review your codebase, dependencies, runtime environment, and integration points to build a picture of what’s working, what’s fragile, and what’s holding you back. That includes configuration files, database schemas, deployment procedures; All the invisible glue keeping things running.

Whether your system is written in VB6, Delphi, classic .NET Framework, or something more obscure like Smalltalk, we work backwards from the behaviour to the code and forward from the code to the risk. We don’t rely on assumptions. We trace execution, test boundaries, and identify both technical and organisational risks.

The goal isn’t to shame your stack. It’s to shine a light on what’s still valuable, and what needs replacing. You don’t need transformation theatre. You need clarity.

Legacy systems often outlast the teams that built them, and the tools that supported them. That doesn’t make them worthless. In fact, their stability might be the very reason your business still runs. But stability without visibility breeds risk. Our job is to turn that black box into a roadmap, separating the brittle from the battle-tested so you can move forward with confidence.

We don’t just read code; We read between the lines. That includes understanding the business logic buried in legacy modules, the tribal knowledge that never made it into documentation, and the knock-on effects of quick fixes layered over time. Our analysis doesn't end with a list of problems; it comes with a hierarchy of what to fix, what to leave, and what to keep an eye on.
