PHP migration · Zurich
PHP upgrade and migration services in Zurich
GDPR-first, fully documented and hosted in the EU, with a senior team working your morning hours.
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.
Swiss companies most often hire us for fintech, healthcare and enterprise software with strong data protection.

Privacy, quality and clear documentation

Documentation you can audit
Written specifications, architecture notes, test reports and handover documents, so your team or auditors can follow every decision.
Accessible by default
Interfaces built to WCAG guidelines, helping you meet the European Accessibility Act for digital products and services.
Predictable contracts
Fixed scope and price, clear milestones and acceptance criteria, and full ownership of the code and IP.
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 Zurich clients
Time-zone overlap
Central European and Indian working days overlap by three and a half to four and a half hours, so your team is online for stand-ups and calls every morning your time.
The Swiss Federal Act on Data Protection (revFADP)
We design to the revised FADP: privacy by design and default, access controls, encryption, data hosted in Switzerland or the EU when you need it, and NDAs and data agreements signed before work starts.
Billing
Invoices in Swiss francs (CHF), euros or US dollars. Typical senior rates are $25 to $49 (USD) per hour, or a fixed price for a defined scope.

Zurich and Zug companies in finance, insurance and crypto work with us on secure platforms and AI, designed to the revised FADP with full source-code ownership.

What we set up for Zurich
Local payments
Languages
Data hosting
AWS Europe (Zurich), Google Cloud europe-west6 (Zurich) and Azure Switzerland North, 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.
