In a nutshell

What is BrightLegacy?

Your organisation probably runs on systems that have been around for years — sometimes decades. They work, but nobody dares to change them. The original developers have left, the documentation is incomplete, and every modification feels like a risk. Meanwhile, maintenance costs rise and integration with new systems becomes increasingly difficult.

BrightLegacy modernises your outdated systems with AI — step by step, zero risk, zero downtime.

Our AI agents first fully analyse your existing system: every line of code, every database table, every business rule. They build complete documentation that probably never existed. Then they modernise the system in small, safe steps — while the old system keeps running. Only when the new version is proven to work correctly does the switch happen.

Why would your organisation want this?

Modernising legacy systems is traditionally one of the riskiest IT projects that exist. Major budget overruns, months of delays, and the risk that the new system doesn't do what the old one did. Many organisations therefore postpone it indefinitely — while costs and risks only increase.

BrightLegacy takes a fundamentally different approach:

  • Zero risk — The old system keeps running until the new one is proven correct. No big bang, no overnight migrations, no unexpected downtime.
  • Complete documentation — For the first time, you get complete, up-to-date documentation of your system — including all business rules that only existed in the code.
  • 70% faster — AI agents work 24/7 on analysis and migration. What normally takes years is completed in months with BrightLegacy.

In short: BrightLegacy makes legacy modernisation feasible — safe, fast, and fully documented.

The problem

Held hostage by outdated systems

Many organisations depend on legacy systems that support critical processes but are barely documented. Costs rise, risk grows, but modernisation seems impossible.

Barely documented

Critical business logic is hidden in code nobody understands anymore. The original developers left long ago.

Too risky to touch

Every change can have unexpected consequences. The system is so intertwined that nobody dares to modernise.

Rising maintenance costs

Specialists for outdated technology are becoming scarcer and more expensive. Costs rise every year, value declines.

Our approach

AI-powered modernisation

Where traditional modernisation takes months to years, we deploy a team of AI agents that analyses, documents, and step-by-step modernises your legacy system.

AI-powered reverse engineering

Our AI agents analyse your complete codebase, database structures, and business processes. They document what was never documented and map hidden dependencies.

Automated code migration

AI agents translate legacy code to modern technology. Not line by line, but with understanding of the underlying business logic.

Data migration & validation

Safe migration of data to modern databases with automatic validation. Every record is checked for integrity and consistency.

Zero downtime guaranteed

The migration proceeds step by step with parallel systems. Your business processes are never interrupted at any point.

Modern architecture

The result: a modern, scalable application with microservices, cloud-native architecture, and built-in AI functionality.

Knowledge preservation

All business logic from the legacy system is documented and preserved in the new application. No knowledge is lost.

The process

From legacy to modern in 4 phases

01

Discovery & analysis

AI agents analyse your legacy system: code, data, integrations, and business processes. You receive a complete report.

1-2 weeks
02

Migration strategy

Based on the analysis, we create a migration strategy: which components first, which technology, which risks.

1 week
03

Step-by-step migration

The AI team migrates component by component. Each part is tested and validated before the next one begins.

4-12 weeks
04

Validation & go-live

Extensive testing, parallel running period, and controlled switchover. Zero downtime, zero data loss.

1-2 weeks
