Modernization & migration · Edinburgh

Application modernization services in Edinburgh

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.

UK businesses most often hire us for AI automation for service businesses, logistics software and fast MVPs for startups.

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.

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.
