Legacy Replacement in Derby
This region industrialised early in software terms too. A great deal of genuinely excellent process knowledge is locked inside systems written decades ago for one business, by someone who has since retired.
Can you replace a legacy system for a business in Derby?
Yes. GTX Digital migrates businesses in Derby off unsupported, undocumented or end-of-life software, in stages, without stopping the operation.
- Starts with documenting the existing behaviour, including the undocumented.
- Migrates in stages, with old and new running together and reconciled.
- Treats data migration and validation as a first-class deliverable.
Derby · Derbyshire
Rail, aerospace and high-value manufacturing
Derby expects software to last, because its products do. A build that cannot be handed over, audited and maintained for a decade is not much use to a business whose output stays in service for thirty years.
Derby has the highest concentration of high-value engineering in the Triangle. Rail manufacturing and aerospace give the city an unusual industrial profile for its size: long programmes, heavy certification, deep supply chains and documentation obligations that outlast the people who created them.
For this work that lands mainly in Automotive manufacturing, Rail engineering and Precision & high-value engineering.

Where it lands
The Derby sectors this work suits.
Drawn from what Derby is actually built on, rather than a list of industries we would accept work from.
-
Automotive manufacturing
Large-scale vehicle production and the component suppliers built around it.
-
Rail engineering
Design, manufacture and maintenance with configuration control and long-term traceability obligations.
-
Precision & high-value engineering
Specialist machining, testing and subassembly, usually to customer-dictated quality systems.
How we work here
What legacy replacement looks like in Derby.
The full scope, phases and deliverables are on the Legacy Replacement service page. These are the parts that are specific to working here.
-
Mapped before replaced
We establish what the system actually does from its data, its outputs and the people who use it, and write it down. Usually the first time anyone has.
-
Incremental, never big-bang
One bounded piece first, reading from the old system while it still runs. A weekend cutover concentrates all the risk into one weekend.
-
Reconciled, not hoped
Rehearsed migrations with reports proving balances, counts and histories match before anything is switched off.
-
Knowledge out of heads
The business rules and the reasons behind them, documented. That often outlives the project and is the most valuable thing produced.
-
On site in Derby
Derby pairs naturally with Nottingham for us, and we will often do both in the same visit. Discovery and the sessions that decide a design happen in person; delivery then runs remotely with scheduled reviews, and there is no travel charge inside the Golden Triangle.
Questions
Legacy Replacement in Derby, answered.
The questions businesses in Derby ask before they commission this work.
What does a legacy assessment cost for a Derby business?
The assessment is a small fixed-price piece of work, typically a few thousand pounds over two to four weeks, producing a written map of the system, a risk register and costed options. It is deliberately standalone: you can take it to any supplier, including ones who are not us.
