Modernization & migration · Luxembourg
Application modernization services in Luxembourg
GDPR-first, fully documented and hosted in the EU, with a senior team working your morning hours.
Clarigo Infotech modernizes and migrates legacy applications so they are secure, fast and easy to change again: PHP upgrades and migrations to modern stacks, Java 8 to Java 17 or 21 with current Spring Boot, .NET Framework to modern .NET, and monoliths split into services where it genuinely helps. We migrate step by step behind a safety net of automated tests, so your business keeps running while the software underneath gets better.
Luxembourg companies most often hire us for fintech, funds and regtech software.

Privacy, quality and clear documentation
European teams tell us they want a partner who treats data protection and quality as the starting point, not an add-on. That is how we work.
GDPR by design
Data minimisation, consent, EU hosting and a signed data processing agreement before any personal data is touched.
Documentation you can audit
Written specifications, architecture notes, test reports and handover documents, so your team or auditors can follow every decision.
Accessible by default
Interfaces built to WCAG guidelines, helping you meet the European Accessibility Act for digital products and services.
Predictable contracts
Fixed scope and price, clear milestones and acceptance criteria, and full ownership of the code and IP.
What we modernize and migrate
PHP upgrades and migration
Old PHP 5 and 7 apps upgraded to PHP 8, or moved to Laravel, Symfony, Node.js or another modern stack.
Java modernization
Java 8 to Java 17 or 21, Spring to current Spring Boot, javax to jakarta, and old app servers to containers.
.NET modernization
.NET Framework and Web Forms to modern .NET, ASP.NET Core and cross-platform hosting.
Monolith to microservices
Split a large codebase into well-defined services, one piece at a time, only where it improves speed or scale.
Front-end modernization
jQuery, AngularJS and server-rendered pages rebuilt in React or Next.js with a modern, accessible UI.
Cloud-native refactoring
Containers, managed databases, queues and serverless, so the app scales and costs less to run.
How we approach Modernization & migration
Why modernize now
Unsupported language versions stop getting security fixes, hosting gets harder, and every new feature takes longer than it should. Modernizing removes that risk and makes the software cheaper to change, without throwing away the business logic that already works.
Rewrite or refactor?
A full rewrite is rarely the safest path. We assess the code and usually recommend an incremental approach: upgrade what can be upgraded, replace the parts that block you, and keep everything that still works. You get a clear recommendation and cost for each option.
No big-bang switchover
We put automated tests and monitoring around the existing system first, then migrate in small, reversible steps, often running old and new side by side. Your users keep working, and every step can be rolled back.
Documented and handed over
You get updated documentation, a CI/CD pipeline and a codebase your own team can maintain. The same engineers can stay on for support and new features.
Built for Luxembourg teams
Time-zone overlap
Luxembourg and Indian working days overlap with India by three and a half to four and a half hours, so your team is online for stand-ups and calls every morning your time.
The GDPR and Luxembourg's data protection law
We design to the GDPR and Luxembourg's 2018 data protection law: data minimisation, consent, access controls, encryption, EU hosting and a data processing agreement signed before work starts.
Billing
Invoices in euros (EUR) or US dollars. Typical senior rates are $25 to $49 (USD) per hour, or a fixed price for a defined scope.
Built for Luxembourg's key sectors
Luxembourg's fintech, funds and regtech companies use us for secure platforms, document automation and AI, designed to the GDPR with EU hosting.
Investment funds
Fund administrators automate reporting and investor onboarding. Customer and field apps are where we usually start here.
Banking and fintech
Payment institutions build EU-wide digital services. Apps for customers, staff and partners, built on one codebase.
Space industry
Satellite operators need data and ground software. We design and ship iOS and Android apps for teams in this sector.
Logistics
Cargo hub operators coordinate freight digitally. Customer and field apps are where we usually start here.

Data hosting
Nearest: AWS Europe (Frankfurt) or Google Cloud europe-west1 (Belgium), in your own cloud account, so data stays where your rules require.
How it works
1. Free assessment
We review your code, dependencies, infrastructure and data, then give you a written migration plan, risks and a fixed quote.
2. Plan and safety net
We add automated tests and monitoring around what exists today, so every change can be checked against the old behaviour.
3. Migrate in small steps
Module by module, with both versions running side by side where needed. You see progress in a demo every week.
4. Cut over and support
A planned switch-over with a rollback path, then the same engineers stay on to fix, tune and keep it current.
