Legacy modernisation
Move off the old system without stopping the business
The system works, but it is slow to change, expensive to host, and the people who built it have moved on. A rewrite from scratch is the option everyone reaches for and the one that most often fails. I modernise incrementally instead — putting the new system alongside the old one, moving functionality across a piece at a time, and keeping you live and shipping throughout. I have done this from Backbone to Angular, from SharePoint to headless React, and from .NET MVC onto a modern stack.
Sound familiar?
- Small changes take weeks and nobody is sure what they will break
- The original developers are gone and the knowledge went with them
- Hosting and licence costs that grow while the system does not
- No tests, so every release is a gamble
What you get
- An honest assessment of what to keep, replace and retire
- A staged migration plan — no big-bang cutover
- The migration itself, shipped in slices that each stand on their own
- Tests and CI around the parts that matter most
Who it’s for
Companies running a business-critical system that is 5–20 years old, still working, and increasingly hard to change.
How it usually runs
Assessment in 1–2 weeks, then migration in slices — each one live before the next starts.
