Legacy modernization without a blackout.
We replace legacy systems without putting live operations at risk.
How this usually shows up
Every change takes weeks
Because nobody understands anymore how the parts fit together.
The software runs on an ageing technology
One you can barely find developers for.
A release takes two days and three people
Because there is no reliable deployment pipeline.
The system still runs, it just cannot move anymore.
Where you end up
Your business runs on a system your team can change again. The old system is switched off without operations stopping for it.
- A running, modernized system
- Documentation of what was carried over and what was rebuilt
- A deployment pipeline for future releases
- Runbooks for operations
From client work
Thanks to fully automated subscription-document generation, we save many hours every week. That lets our team focus entirely on client business instead of manual routine work.
How we go about it
01 / ASSESSMENT
We understand what exists.
We understand what the existing system actually does today, including the parts nobody documented.
02 / SEQUENCING
We break it into sections.
We break the modernization into sections that can each ship independently, instead of one big-bang project.
03 / REBUILD
We rebuild section by section.
We rebuild section by section, keeping the old and new systems running in parallel.
04 / CUTOVER
We switch off the old system.
We switch off the old system once the new one carries the full load.
Team shape, cadence and handover in detail are covered on the How we build page.
Frequently asked questions
No. We sequence the modernization so old and new systems run in parallel until the cutover is safe.
That is the normal case with legacy systems. Part of our work is reconstructing the system's actual behavior, not just reading outdated documentation.
Grown custom software in production, regardless of the original technology stack.
That is part of the architecture review beforehand. We assess each part of the system individually instead of rebuilding everything by default.

Let's talk about the system nobody wants to touch.
Even if the documentation is gone and nobody remembers why it was built that way.
