Legacy Systems Modernisation & Custom Solutions

Legacy Systems Modernisation and Custom Solutions

Legacy systems modernisation and custom solutions become essential when framework dependencies lapse, technical debt accumulates, and your software gradually slows down, becoming increasingly expensive and restrictive to maintain. Outdated applications and fragmented systems threaten operational revenue and constrain core workflows.

At Laramate GmbH, our senior PHP and Laravel architects specialise in architecture modernisation, legacy system migrations and long-term support. We take over brownfield development projects and upgrade existing infrastructure milestone by milestone, with continuous code access and strict automated testing throughout, ensuring operational continuity, zero data loss and complete software ownership.

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.”

Be on a lookout for

Legacy System Modernisation Symptoms

Technology Constraints & Poor Usability

Your underlying stack is rigid, making intuitive interfaces or modern features almost impossible.

Drastic Drop in Feature Velocity

Simple feature updates that used to take days now require weeks due to coupled architectures and undocumented logic across your legacy systems.

Single-Developer Dependency

Project backlogs accumulate while a single developer spends 100% of their time fixing operational bugs instead of delivering software improvements.

Locked Dependencies & Unpatchable Databases

Libraries, frameworks and databases cannot be updated without breaking other services.

Legacy System Modernisation vs. Legacy System Migration

Strategic Dimension

Legacy System Modernisation (Refactoring In-Place)

Legacy System Migration (Transitioning to a New System)

Core Objective

Modernize, clean up, and optimize the existing codebase while maintaining the current platform structure.

Build a modern replacement alongside or on top of the old stack and transfer operations cleanly.

Architectural Execution

Refactor modules, fix technical debt, and upgrade PHP/Laravel versions within the existing codebase.

Deploy a fresh codebase using patterns like the Strangler Fig Pattern, linking systems via bidirectional APIs during transition.

Data Handling

In-place schema migration and database cleanup inside your existing legacy database.

Complex, zero-loss data ETL (Extract, Transform, Load) pipelines to move records to a modern database architecture.

Development Approach

High-coordination engineering directly inside the live repository to avoid code conflicts.

Parallel buildout allowing fresh greenfield development while the legacy platform remains active alongside.

Ideal For

Applications with sound core architecture that need technical debt removal, safety tests, and framework upgrades.

Systems constrained by obsolete technologies, unfixable UI/UX bottlenecks, or severe architectural limitations.

Complex legacy system modernisation and migration

Legacy Systems We Modernise & Migrate

Legacy APIs & Batch Processing Systems

Upgrading old file-exchange systems, cron jobs, ETL pipelines, and API gateways to real-time REST/GraphQL architectures.

Custom Auth, Identity & SSO Implementations

Replacing fragile, custom login mechanisms with secure OAuth2, SAML, and modern Identity Access Management (IAM) standards.

Legacy Enterprise Platforms (ERP, CRM, LMS)

Rebuilding bloated, hard-to-use business software into custom web applications that mirror your exact workflows.

Legacy Databases & Data Warehouses

Executing secure schema migrations and restructuring database setups without data loss.

Monolithic Web Applications & Custom Legacy Code

Converting rigid, undocumented PHP/web monoliths into modern, scalable architectures.

Legacy Desktop Software & On-Premise Installations

Transitioning legacy desktop applications into cloud-hosted web platforms and customer portals.

Hybrid & Outdated Cloud Architectures

Migrating early-stage AWS, Azure, or GCP deployments to optimized containerized hosting environments.

YOUR SUCCESS

You get priority handling and dedicated attention. 1 team → 1 → project → 1 outcome

Why Us

We’re off to a fantastic start

Because Laramate's process protects your investment

01

No Middlemen or Account Buffers

Hop on a call with Chris

You or Stakeholders are in direct contact with our senior developers during the development sprints. We eliminate the telephone-game miscommunications that plague traditional 100-person agencies.

02

Roadblock Prevention

Don't sit on your project

We draft the full system architecture map before deep implementation. We ensure your core database schema is built for scale. Your product can evolve, add multi-tenant features, or chain new modules together down the line without requiring a costly re-platforming rewrite.

03

Project Lifecycle Partners

Zero Bias

We are not tied to a "build-only" mentality. By mastering both greenfield and brownfield projects, we provide objective advice on when it makes sense to innovate, optimise your existing systems, or resolve technical debt, and implement new features. We ensure your software remains an asset, not a liability, at every stage of its lifecycle.

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.
