Modernization & migration · South Africa

Application modernization services in South Africa

Mobile-first, low-bandwidth products with mobile money built in, from a senior team on overlapping 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.

South African companies most often hire us for fintech, healthcare software and AI automation.

What matters to South Africa teams

Mobile-first and built for real conditions

African businesses need products that work on any phone and any connection, with mobile money and local payments built in.

01

Works on any connection

Lightweight apps and sites that stay fast on slow networks and older phones.

02

Mobile money and local payments

M-Pesa, Flutterwave, Paystack and card payments integrated.

03

Overlapping hours

Two and a half to four and a half hours from India, so most of the day overlaps.

04

Cost-effective delivery

Senior engineers at offshore rates with full code ownership.

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.

Working with us from South Africa

Built for South African teams

Time-zone overlap

South Africa is three and a half hours behind India, so our working days overlap for most of your morning and early afternoon.

The Protection of Personal Information Act (POPIA)

We design to POPIA's conditions for lawful processing: purpose limits, security safeguards and data-subject access, with data hosted in South African cloud regions when required. We sign NDAs before work starts.

Billing

Invoices in South African rand (ZAR) or US dollars. Typical senior rates are $25 to $49 (USD) per hour, or a fixed price for a defined scope.

Data hosting

AWS Africa (Cape Town), Google Cloud africa-south1 (Johannesburg) and Azure South Africa North, 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.
