Upgrade Legacy PHP, Laravel & CodeIgniter Projects
Running PHP 5/7, Laravel 5–8, or CodeIgniter 2/3? Your app has known security vulnerabilities and is no longer receiving patches. I migrate legacy codebases to modern, secure versions — without downtime or data loss.

PHP 5.6 reached end-of-life in 2018. PHP 7.4 in 2022. PHP 8.1 in December 2025. If your app is still on any of these, it has unpatched CVEs and no security fixes — every day is a liability.
Upgrade paths I handle
- PHP 5.4 / 5.6 / 7.0 / 7.2 / 7.4 / 8.1 / 8.2 / 8.3 → PHP 8.5 (latest, active support)
- Laravel 4 / 5.x / 6.x / 7.x / 8.x / 9.x / 10.x / 11.x → Laravel (latest stable)
- CodeIgniter 2 / CodeIgniter 3 → CodeIgniter 4.7 or full Laravel rewrite
- CakePHP 2 / 3, Symfony 3 / 4 → modern equivalents
My upgrade process
- Audit first — full code and dependency review, security vulnerability report
- Incremental migration — never a big-bang rewrite that risks breaking everything
- Test before touching — add test coverage around critical paths first
- Zero downtime — blue-green or rolling deployment strategy
- Documentation — architecture decisions written up for your team
Why upgrade now?
- End-of-life PHP versions have unpatched CVEs exploited in the wild
- Hosting providers are dropping support, breaking deployments
- Modern PHP 8.x is 2–3× faster than PHP 5.x — your users will notice
- New developers refuse to work on legacy stacks — you lose hiring power
