PHP upgrade and migration services in Hong Kong
A senior team a short time-zone hop away, building products ready to scale across the region.
Clarigo Infotech upgrades and migrates legacy PHP applications: PHP 5 and 7 to PHP 8, hand-written PHP to Laravel or Symfony, old CMS and framework versions to supported ones, or a full move to Node.js or another stack when that is the better long-term choice. We add tests first, then upgrade step by step, so the site or app keeps working throughout.
Hong Kong companies most often hire us for fintech, trading and logistics platforms, and AI.

PHP version upgrades

Framework upgrades
Old Laravel, Symfony, CodeIgniter, CakePHP and Zend versions brought up to supported releases.
Legacy PHP to Laravel
Unstructured PHP code reorganised into a clean, tested Laravel or Symfony application.
PHP to Node.js or other stacks
A planned migration to Node.js, Python or another stack when it fits your team and roadmap.
Database and hosting
MySQL upgrades, query fixes, and a move from shared hosting to containers or the cloud.
Security and performance
Security patches, dependency updates, caching and profiling so the app is safe and fast.
How we approach PHP migration
Why PHP upgrades can't wait
Older PHP versions no longer receive security updates, and many hosts and libraries are dropping support. An upgrade closes known vulnerabilities and usually makes the application noticeably faster.
Tests before changes
Legacy PHP rarely has tests. We add them around the most important flows first, so we can prove the upgraded version behaves exactly like the old one.
Built for Hong Kong teams
Time-zone overlap
Hong Kong is two and a half hours ahead of India, so our working days overlap for most of the day.

We design to the PDPO's data protection principles: purpose, accuracy, security and access, and we sign NDAs before work starts.

AWS Asia Pacific (Hong Kong), Google Cloud asia-east2 and Azure East Asia, in your own cloud account, so data stays where your rules require.
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.
