PHP migration · Japan

PHP upgrade and migration services in Japan

Detailed specifications, careful testing and reliable schedules, with a team overlapping most of your afternoon.

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.

Japanese companies most often hire us for AI automation, enterprise systems and mobile apps.

What we do

What our PHP migration covers

PHP version upgrades

PHP 5.x and 7.x to PHP 8, fixing deprecated functions, extensions and incompatible libraries.

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.

In depth

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.

Working with us from Japan

Built for Japanese teams

Time-zone overlap

Japan is three and a half hours ahead of India, so our working days overlap for most of your afternoon, with a stand-up and same-day replies.

Japan's Act on the Protection of Personal Information (APPI)

We design to the APPI: clear purpose of use, security controls, rules for third-party and cross-border transfers, and data hosted in Japanese cloud regions when required. We sign NDAs before work starts.

Billing

Invoices in Japanese yen (JPY) or US dollars. Typical senior rates are $25 to $49 (USD) per hour, or a fixed price for a defined scope.

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.
