Legacy Modernization – references from maintenance and migration
Here you'll find selected case studies on legacy modernization: from Delphi to the cloud and software rescue to data migration – built in East Frisia, Made in Germany.
What we modernize
Keep the base, reduce risk, renew step by step
Grown software is often the backbone of day-to-day operations — and hard to maintain at the same time. We open the base via interfaces, reduce technical debt and migrate module by module instead of risking a big-bang rewrite.
Modernize Delphi
Keep productive Delphi systems and extend them with REST interfaces, cloud connectivity and offline sync — without a risky full rebuild.
To the serviceReplace COBOL & VB6
Step-by-step migration of outdated platforms into modern, maintainable architectures — with clear phases instead of a big bang.
To the serviceSoftware rescue & analysis
Stabilize inherited code, repair builds and tests, and assess code bases transparently for due diligence.
To the serviceReference projects
Nine case studies from legacy practice
From Delphi development and COBOL and VB6 replacement to software rescue — these projects show how legacy systems can be renewed during ongoing operations.

Logistics: Delphi dispatching to the cloud
Replacing an error-prone Delphi dispatching system with a cloud-based web application, a PWA for drivers, REST interfaces and a step-by-step migration — with measurable time and cost savings.

Book a consultationWhy legacy modernization has to happen step by step
Short answer for decision-makers: Legacy systems often run the day-to-day business but block new requirements, interfaces and compliance. Instead of a risky full rebuild, we modernize iteratively — with clear phases, stable operations and measurable milestones, developed in East Frisia, Made in Germany.
Typical starting points
We frequently see the same patterns: a central Delphi application that has run for years but lacks modern interfaces; COBOL or VB6 programs without a maintenance perspective; or a half-finished project after a service provider left.
In all these cases, the base is too valuable to switch off — and too fragile to keep running without a plan. A legacy code analysis first creates transparency about risks and effort.
Our approach
We separate analysis, interface opening, step-by-step migration and operations. Where possible, the productive legacy system stays the leading source while new functions are added via REST interfaces or cloud components. This creates traceable milestones instead of an all-or-nothing risk.

Approach & cost-effectiveness
What do these legacy references say about how you work?
When is modernization worth more than a rebuild?
If a legacy system still serves the business but fails on interfaces, maintainability or platform, step-by-step modernization is usually cheaper and lower-risk than a full rebuild. We open the base via APIs, extract sub-functions and migrate module by module. We only recommend a complete rebuild when the architecture or technology is no longer viable.
