Modernization & migration · Sweden

Application modernization services in Sweden

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.

Swedish companies most often hire us for SaaS, mobile apps and AI products.

What matters to Sweden teams

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.

01

GDPR by design

Data minimisation, consent, EU hosting and a signed data processing agreement before any personal data is touched.

02

Documentation you can audit

Written specifications, architecture notes, test reports and handover documents, so your team or auditors can follow every decision.

03

Accessible by default

Interfaces built to WCAG guidelines, helping you meet the European Accessibility Act for digital products and services.

04

Predictable contracts

Fixed scope and price, clear milestones and acceptance criteria, and full ownership of the code and IP.

What we do

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.

In depth

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.

Remote, but close to Sweden

Swedish and Indian working days overlap 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 the Swedish Data Protection Act

We design to the GDPR and Sweden's supplementary Data Protection Act: data minimisation, consent, access controls, encryption, EU hosting and a data processing agreement signed before work starts.

Data hosting

AWS Europe (Stockholm) and Azure Sweden Central, in your own cloud account, so data stays where your rules require.

Process

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.
