Legacy system rescue

The company that built your system is gone.
Your business still depends on it.

Old Access databases, Visual Basic 6 programs and bespoke systems from software houses that no longer exist still run a surprising number of UK businesses. We work out what yours actually does, recover the data and the business rules, even without the source code, and replace it with a modern system before it fails.

Signs your business is running on borrowed time

What we work with

If it’s old, we’ve probably seen it

We can read data and logic out of most of the technologies UK businesses built on in the 1990s and 2000s, including formats that modern tools refuse to open.

How it works

From “nobody knows how it works” to a system you own

1

Assess

We take a copy of the system and its data and find out exactly what it does, what’s recoverable and where the risks are.

2

Recover

We extract every table, report and business rule, often directly from the compiled program, so nothing is lost or guessed.

3

Rebuild

We build a secure, modern, UK-hosted replacement around how your team actually works, with no per-seat licence fees.

4

Migrate

We bring across your full history and run both systems side by side until you’re confident to switch over.

Recent work

A 30-year-old system with no source code and no supplier

Engineering spares depot, south coast

The depot’s stock system was written in 1995 in Visual Basic 6 on an Access 97 database. The company that built it had long since closed, there was no source code, and the database format is one modern Microsoft tools can no longer open. Yet the business is contractually obliged to track the full history of every item for decades.

  • We recovered the system’s database queries directly from the compiled program
  • We mapped all 32 tables and the document templates that produce signed, contractual paperwork
  • We turned what we found into a full specification and a fixed-scope replacement plan
  • The new cloud-based system is now in build, with every historic record coming across

The Legacy System Assessment

A fixed-price investigation, agreed before we start, that tells you exactly where you stand before you commit to anything bigger.

  • What your system actually does: screens, reports, rules and data
  • What can be recovered, and how confident we are
  • A plain-English risk rating: how likely it is to fail, and what happens if it does
  • Your options: stabilise, replace, or a phased mix, with a realistic budget for each

Your data is handled under a confidentiality agreement, stays in the UK and never leaves our environment. We are ICO registered.

Questions we’re often asked

Before you get in touch

We don’t have the source code. Is that a problem?

Usually not. The data is in the database, and a surprising amount of the logic can be read out of the program itself. Where it can’t, we watch the system running and document what it does.

Will we lose our history?

No. Migrating every historic record is part of the job, not an optional extra. For many of our clients, that history is the whole point.

Do we have to stop using the old system?

Not until you’re ready. We run the old and new systems in parallel and only switch over once your team is happy.

Is this only for big companies?

No. Most of the systems we see are used by somewhere between 3 and 30 people. That’s exactly why off-the-shelf software never quite fitted in the first place.
