PHP upgrade and migration services in Tokyo
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 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.
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.
How we work with Tokyo clients
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.
Industries we work with in Tokyo
Tokyo companies work with us on AI automation, enterprise systems and mobile apps, with detailed specifications, thorough testing and regular written reports.
Automotive
Carmakers invest in connected-car software and factory automation. We build the platforms, integrations and internal tools this sector relies on.
Electronics and robotics
Hardware makers need companion apps and embedded AI. Custom software that fits how these teams already work.
Gaming and anime
Entertainment firms reach global fans through apps and stores. From internal tools to customer platforms, built and supported by one team.
Retail and convenience
Chains run loyalty apps and cashless checkout. We build the platforms, integrations and internal tools this sector relies on.

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.

Which currency do you bill in, and what does it cost?+
We bill in Japanese yen (JPY) or US dollars. Senior engineers typically cost $25 to $49 (USD) per hour, and fixed-scope projects such as an MVP in 25 to 30 days are quoted after a free consultation.

Usually in AWS Asia Pacific (Tokyo, Osaka) and Google Cloud asia-northeast1 (Tokyo), or wherever your data rules require. Everything runs in your own cloud account, so you stay in control.
