Many CodeIgniter applications were built years ago and now hold businesses back: they struggle with current PHP versions, lack automated tests and are hard to hire for. CSNexa audits your CodeIgniter codebase, recommends the right path — migrate to Laravel, upgrade to CodeIgniter 4, or modernise in place on PHP 8 — and delivers it in phases at a fixed price.
Who it's for
- Businesses running CodeIgniter 2 or 3 applications that struggle with current PHP versions
- Teams that find it hard to hire developers for an ageing CodeIgniter codebase

Full migration to Laravel
Rebuild your application module by module on Laravel, keeping the same database and URLs where possible so users notice nothing but a faster, more reliable app.
Upgrade to CodeIgniter 4
If you want to stay on CodeIgniter, we upgrade CodeIgniter 3 applications to CodeIgniter 4 and modern PHP, resolving breaking changes along the way.
PHP 8 compatibility in place
When a migration is not yet affordable, we make your existing CodeIgniter app run safely on a supported PHP version as a first step.
Technologies we use
How we deliver
Free code audit
We review your codebase, PHP version, dependencies, database and hosting, and identify risks and quick wins.
Migration plan
You receive a phased plan — which modules move first, how data is migrated and how we avoid downtime — with a fixed price.
Phased migration
Modules are migrated one at a time, with the old and new code running side by side where needed, so the business keeps running.
Testing and verification
Automated tests and data checks confirm every migrated module behaves exactly like the original.
Cutover and handover
Planned switch-over, monitoring, documentation and an optional maintenance plan.

Frequently asked questions
Should I migrate from CodeIgniter to Laravel or upgrade to CodeIgniter 4?
It depends on your application and plans. Laravel offers a larger ecosystem and hiring pool; CodeIgniter 4 can be a smaller step for simple apps. Our free audit compares both options for your codebase and recommends one.
Will my application go offline during the migration?
We plan migrations in phases so the business keeps running. Modules are moved one at a time and the final cutover is scheduled at a quiet time, with a rollback plan.
What happens to my existing data?
We write migration scripts and verify the data after each stage. In many projects the existing database can be kept, with only the application code replaced.
How long does a CodeIgniter to Laravel migration take?
It depends on the size and condition of the codebase. Small applications can take a few weeks; larger systems are planned over several months in phases. The audit gives you a timeline before you commit.
How much does it cost?
After the free code audit we give you a fixed-price quote for the agreed scope, so there are no surprise invoices.
Do you maintain existing CodeIgniter applications?
Yes. If you are not ready to migrate, we take over maintenance of your CodeIgniter 3 or 4 application: bug fixes, small features, security and PHP compatibility updates, on a monthly plan.
Can you just make my CodeIgniter app work on PHP 8 for now?
Yes. If a full migration is not the right step yet, we can upgrade your application to run on a supported PHP version as a first phase.
