Most South African businesses have at least one critical system running on old infrastructure — a custom-built VB6 application, a 15-year-old ASP system, a Delphi job management tool that only one person knows how to fix.
Legacy Modernisation | South Africa
Migrate Off Your Legacy System Before It Fails You
Old software running on Windows XP servers with no support contract is a ticking risk. We get you off it — safely, with all your data intact.
Service
The hidden cost of keeping legacy systems alive
The risk compounds every year: vendor abandonment, security vulnerabilities, incompatibility with modern operating systems, and an ever-shrinking pool of developers who can work on the old technology.
We specialise in deconstructing legacy systems — understanding the business logic buried in old code — and rebuilding them on modern, maintainable platforms without disrupting your operations during the transition.
Service
What legacy modernisation covers
Legacy system audit and risk assessment
We document what your legacy system does, what data it holds, what the critical failure points are, and what a migration needs to preserve.
Data extraction and migration
We extract data from old databases (Access, Paradox, dBase, FoxPro, legacy SQL), clean it, and migrate it to a modern schema with zero loss.
Business logic replication
The calculation rules, rounding logic, and edge cases buried in 15-year-old code matter. We document and replicate them faithfully before we refactor.
Parallel running and validation
We run old and new systems simultaneously before cutover, comparing outputs and resolving discrepancies until the new system is confirmed accurate.
Modern platform rebuild
We rebuild on a current technology stack — PHP 8.2+, Node.js, Python, or your preference — with proper version control, testing, and documentation.
Training and handover
User training on the new system, full technical documentation, and a support period after cutover.

FAQs
Questions you probably have.
How do you handle legacy systems where no documentation exists?
We reverse-engineer the business logic from the source code and database structure. We interview your longest-serving staff to map every process, edge case, and workaround. This takes longer but produces a complete picture before we build.
What if the old system is still being actively used during migration?
We run parallel systems during transition. The old system stays live until the new one is validated. Cutover happens in a planned maintenance window, typically a weekend, with rollback capability.
Can you migrate from Microsoft Access databases?
Yes. Access is one of the most common legacy platforms we encounter in South African businesses. We extract the data, migrate to PostgreSQL or SQL Server, and rebuild the application on a modern web or desktop platform.
How do you preserve years of historical data?
Historical data migration is a core part of every modernisation project. We archive complete historical records, validate them against the source, and ensure they are queryable in the new system.
What technology do you recommend for the new system?
It depends on your team and hosting environment. For most South African business systems we build on PHP (Symfony) or Node.js backend with a React or Vue.js frontend. We tailor the choice to your long-term maintainability needs.
