Does this sound familiar?
CI3 is End-of-Life
No more security updates. Every new PHP version could break your app.
Hoster pushing PHP 8
PHP 7.4 is being shut down and your CI3 app is not compatible.
Hard to find developers
Hardly anyone wants to touch CI3 code anymore. New features get expensive.
Migration postponed
You know it is necessary – but who should do it? And what does it cost?
I work with CodeIgniter daily
This website runs on CodeIgniter 4. I have been using the framework for over 11 years – from CI2 through CI3 to today's CI4. The migration is not rocket science, but it needs someone who knows both worlds.
CI4 is a complete rewrite – not a simple update. Namespaces, PSR-4 autoloading, new routing. I know where the pitfalls are and how to avoid them. Your custom libraries? I migrate them too. Your data? Stays intact.
From CI3 to CI4 – completely modernised
Modern code with namespaces
Your code is migrated to the new CI4 architecture. PSR-4 autoloading, namespaces, modern structure. No more legacy baggage.
- PSR-4 Autoloading – Standard-compliant structure
- Namespaces – Clean code organisation
- MVC 2.0 – Entities, Models, Services
- PHP 8.x – Typed Properties, Attributes
Custom code comes along
Your own libraries, helpers and plugins don't disappear. I port them to CI4 standards – clean, tested, documented.
- Custom Libraries – Adapted to CI4 namespaces
- Helper Functions – Modernised and typed
- Third-Party Code – Composer integration where possible
- Documentation – What was migrated how
Future-proof and maintained
CI4 is actively developed. Security updates, new features, community support. Your app is secured for years again.
- Active Support – Regular security updates
- CSRF Protection – Improved security features
- Content Security – CSP Headers support
- Composer – Easy updates via CLI
CodeIgniter is my daily driver
Own CI4 projects
This website, client portals, APIs – I use CI4 daily and know every corner.
CI3 veteran
I have worked with CI3 for years and know how the old code works.
Direct communication
No project manager in between. You talk directly with the person writing the code.
Fixed-price guarantee
After the analysis you get a fixed-price offer. No surprises.

I migrate on a staging environment. Your live app keeps running.
Go-Live
After testing and sign-off, the new version goes live. Documentation included.
"Our CI3 application was 8 years old and nobody wanted to touch it. Vincent migrated it to CI4 in 3 weeks – including all custom libraries. It now runs on PHP 8.2 and is significantly faster."
