How do you ensure historical business logic is preserved?

We capture documented and previously implicit business rules with domain experts. Characterization and integration tests protect the captured workflows against regressions. Unknown edge cases remain a risk, reduced through test data and business acceptance.

Which tech stacks can be modernised?

Typical projects involve aging PHP monoliths (Zend, legacy Symfony, bespoke frameworks), monolithic Java/Spring applications or Node.js systems, migrating toward modern TypeScript, Next.js, Go or C#/.NET.

What is included in the Modernisation Audit?

The audit is a fixed-price package: We analyze architecture, codebase health, database bottlenecks and security risks, delivering a prioritized decision matrix with clear milestones and time estimates.

LEGACY MODERNISATION & REFACTORING

Legacy Software Modernisation

Renew existing systems incrementally. Plan migration, cutover and rollback in advance.

Outdated software binds engineering resources, halts product innovation and increases failure risks.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.

Scope & next step

Understand the existing system before planning its replacement

When it fits: For business-critical applications with difficult-to-maintain rules, ageing integrations or growing change risks. A complete rewrite is an option, never the default recommendation.
What you receive: A system and dependency map, documented risks and a comparison of refactoring, incremental replacement and a rewrite. The next migration step gets validation and rollback criteria.
How we begin: We limit the assessment to agreed components. We need a business-rule contact, a system overview and approved access to code, test data and a suitable test environment. Scope and price are confirmed first.

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 old components incrementally. Cutover and parallel operations are coordinated with business and technical requirements.

Modern APIs & Interfaces

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

Safe Data Migration

Data migration with agreed validation rules, checksums and tested rollback procedures.

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.

New components can often be built in parallel and introduced incrementally. Maintenance windows depend on the database, integrations and operations. We plan tests, cutover and rollback in advance and agree on remaining risks with you.
