Application modernization services in Dublin
Senior engineers on your morning and lunchtime hours, UK GDPR built in, and a fixed price before we start.
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.

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.
How we work with Dublin clients
Time-zone overlap
Irish and Indian working days overlap by four and a half to five and a half hours, so stand-ups, calls and quick decisions happen during your morning and early afternoon.
The GDPR and the Irish Data Protection Act 2018
We design to the GDPR and the Data Protection Act 2018: 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.

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.
