LEGACY MODERNISATION & REFACTORING

Legacy Software Modernisation

Incrementally renew existing systems – with zero downtime and zero data loss.

Outdated software binds engineering resources, halts product innovation and increases failure risks. ProjectMakers modernises your legacy codebase step-by-step using proven architecture patterns, secures core business logic with automated test suites and integrates modern APIs.

Our Approach to Modernisation

No high-risk big-bang rewrites, but controlled, measurable progress.

Architecture & Risk Audit

We analyze your system architecture, dependencies, databases and critical code paths.

Safeguard Business Logic

Historically grown business logic is isolated, documented and protected by automated regression tests.

Incremental Migration

New modules replace obsolete components step-by-step (Strangler Fig Pattern) while production stays fully online.

Modern APIs & Interfaces

We expose proprietary legacy systems via modern REST, GraphQL or event streams for cloud and web.

Safe Data Migration

Zero data loss migrations with cryptographic checksums, validation pipelines and proven rollback plans.

Future-Proof Tech Standards

Upgrade to modern stacks (TypeScript, Next.js, C#/.NET, Kotlin, Docker) with complete documentation and handover.

Clear Starting Point

Starting Point: Architecture & Modernisation Check

Before investing in costly rewrites, we inspect your codebase and dependencies. You receive an objective assessment: Refactoring vs. rewrite, critical risk areas and an actionable roadmap.

FAQ

Frequently Asked Questions: Modernisation

Clear answers about process, risk mitigation and continuous operations.

No. We primarily use the Strangler Fig Pattern: Your legacy system continues operating smoothly in production. New components are built in parallel and transitioned gradually after automated verification – with zero planned downtime.
