Legacy Application Modernisation

Legacy Application Modernisation For Enterprise Businesses

Legacy application modernisation for enterprise businesses helps you replace outdated components without the cost and risk of a complete system replacement.

When your inventory system is outdated, your software is difficult to change, or a full replacement feels too risky, Laramate helps you modernise existing applications one process or module at a time. We keep essential business data and existing functionality working alongside new components as your system changes.

We assess your existing architecture, identify dependencies and prioritise the parts that need to change. By integrating new functionality with your existing systems and testing it against established business behaviour, we help you replace outdated components without unnecessarily disrupting daily operations or breaking critical integrations.

Whether you need incremental legacy system modernisation, want to reduce technical debt across an existing application, or are planning a complete replacement, we help you determine the most practical path forward.

Legacy Application Modernisation Symptoms

When Does Your Application Need Modernisation?

Increasing Technical Debt & Degraded Usability

A rigid underlying architecture makes modernising user interfaces or adding intuitive features nearly impossible. As quick fixes and workarounds accumulate over time, the codebase becomes fragile, difficult to test, and slow to extend.

We assess your system, identify issues, strip away unnecessary complexity, and prioritise refactoring where it delivers immediate business value.

Outdated PHP, Laravel, or Core Dependencies

Running unsupported framework versions leaves your application exposed to security risks and blocks your team from adopting modern tooling.

We evaluate your current stack, isolate breaking changes, resolve deprecations, and manage smooth version jumps across PHP and Laravel releases to keep your core business systems fully supported, secure, and protected.

Handover from a Previous Development Partner

If your previous agency is unresponsive or project progress has stalled, we step in to take over your live application. Through a structured codebase audit and a technical onboarding process, we identify what works, patch urgent security risks, and safeguard your day-to-day business continuity.

Locked Dependencies & Unpatchable Databases

When databases, PHP extensions, and packages are tightly locked to legacy code on unsupported versions, updating one component risks taking down the entire platform.

We map out version conflicts, modernise legacy database structures, and implement isolated service layers to ensure patching databases and upgrading core libraries won't crash your live operations.

Systems That No Longer Work Well Together

Disconnected business tools, isolated databases, and manual CSV exports drain productivity and introduce human error. We eliminate operational silos by building stable, versioned APIs and automated data pipelines to secure accurate information flow across your applications.

Good to know

Laramate's Codebase Policy

Handing over an active codebase to a new agency can feel highly risky.

Our support and maintenance contracts provide continuous technical assistance and consulting, including bug fixes, regular security updates and personalised guidance.

— Team Laramate
“We require full access to any existing codebase under NDA upfront so we can assess its technical health. If that’s not possible, we include a mutual walk-away clause. Some projects prove unmaintainable due to heavy technical debt or serious security issues.”

What Laramate Can do for you

Incremental Legacy Application Modernisation
Phased Processes

Strategy When It Makes Sense Approach & Risk Budget & ROI
Phased Modernisation (Brownfield) An established system runs core operations, but technical debt or legacy code blocks new features. Operational downtime is not an option. Approach: We apply the Strangler Fig pattern. New services and modern Laravel components are built alongside the legacy software. User traffic routes to modern components step by step until the new platform replaces the old system. Risk: Low and controlled. Each service release is isolated, tested, and deployed without taking the core business offline. Staged Investment: Costs spread across clear delivery milestones. Each updated module delivers immediate operational value without an all-or-nothing release risk.
Greenfield Development (From the Ground Up) You are launching a new digital product, custom platform, or internal business tool. Approach: We architect and develop the entire platform from a blank slate using modern Laravel standards, scalable database structures, and clean APIs. Risk: Standard product launch scope. No legacy workarounds or data migrations required. Focus stays on validation, clean code, and fast time to market. Focused Product Budget: Capital targets pure feature development and modern architecture, with zero budget spent on untangling legacy technical debt.

We’re off to a fantastic start

FAQ

Questions remaining?

Yes. We offer both maintenance packages and ongoing support to keep your software up to date and fully functional, always on terms tailored to your project. Find out more here.

Even smaller projects and content-only websites need regular updates. Once initial development is complete, we recommend transitioning to a maintenance contract. We handle monthly software updates and functional checks. This is an investment in the security and reliability of your project.

No. We are happy to assist with selecting and setting up the right server or system architecture. We recommend Hetzner as an infrastructure provider (we have no affiliation with Hetzner).

Your advantage: there is no vendor lock-in. You sign the contract directly with Hetzner (or any other provider) and we handle the administration and management.

If development effort in a given month exceeds the agreed-upon hours, the additional time is billed at our standard agency hourly rate.

If there is little or no need for development in a particular month, up to 50% of the unused hours roll over to the following month. Accumulation of hours across multiple months is not possible.

Yes, this is one of our core competencies. Using a bespoke Laravel backend, we securely connect your software to third-party systems such as Microsoft Dynamics 365 Business Central, HubSpot, or custom databases.

Before implementation, we thoroughly analyse how best to integrate with your existing systems. Our automation solutions are also designed to fit seamlessly into your current infrastructure.

Yes. We integrate Filament into existing projects as well. Whether you need an admin dashboard, process automation, or extended functionality — retrofitting is straightforward and hassle-free.

Yes. Alongside development, we also offer long-term support, regular updates, and assistance with the ongoing evolution of your applications.

No!

Our engagement model prioritizes client autonomy.  We deliberately avoid creating vendor lock-in through proprietary dependencies or opaque implementations.

Yes, of course. We’ll guide you through the entire review process for the Apple App Store and Google Play Store and ensure that all technical guidelines and data protection requirements are met, so that your app can be published without a hitch.

We primarily use React Native and Expo to build a shared codebase for iOS, Android, and macOS. This saves time and cost without compromising on performance or user experience. The result feels fully native to the end user.

If your app requires complex server-side logic, we connect a Laravel backend via API. Laravel is our speciality and enables secure, scalable backends for your application.

We believe in transparent communication and use tools like Slack, Trello, or Jira to track project progress and provide regular updates. For longer-running projects, we also hold regular check-in meetings to ensure we stay aligned.
