Legacy PHP modernization

Legacy PHP modernization & Laravel migration.

Aging PHP and Laravel applications don't have to be rewritten to be saved. We assess inherited and outdated codebases, get them onto supported PHP and Laravel versions, add the tests and structure that make change safe again, and bring business-critical systems back to a state where shipping features stops being a risk.

Who this is for

For businesses depending on software that has aged out.

This service fits businesses that rely on an existing PHP or Laravel application that has fallen behind: outdated versions, no tests, mounting technical debt, or a system nobody on the current team wants to touch.

  • You inherited a PHP or Laravel application and nobody on the current team is comfortable changing it.
  • The app runs the business, but it is stuck on an old PHP or Laravel version that blocks upgrades and security patches.
  • Every new feature takes far longer than it should, and small changes break things in unexpected places.
  • The original developer or agency is gone, and you need someone senior to take over the codebase.
  • You are weighing a full rebuild against fixing what you already have, and you want an honest assessment first.
  • Hosting, dependencies, or a framework end-of-life deadline is forcing the issue.

What we modernize

Types of applications we modernize.

  • Legacy PHP applications
  • Outdated Laravel versions
  • PHP-to-Laravel migrations
  • Custom in-house frameworks
  • CodeIgniter / CakePHP / Zend apps
  • Abandoned or inherited codebases
  • Apps stuck on old PHP versions
  • Brittle, untested codebases
  • Slow or unstable applications
  • Insecure or unpatched systems
  • Tangled business logic
  • Apps with no deployment process

Common problems

Problems modernization solves.

Modernization makes sense when an application still matters to the business but has become slow, risky, or expensive to change, and replacing it outright would be more disruptive than fixing it.

  • The application is stuck on a PHP or Laravel version that no longer receives security updates.
  • Dependencies are years out of date and can no longer be upgraded safely.
  • There are no tests, so every change is a gamble.
  • The codebase has grown tangled, and changes in one place break another.
  • Performance has degraded as data and usage have grown.
  • Only one person understood the system, and they are no longer available.
  • A hosting change, framework end-of-life, or audit has made the risk impossible to ignore.

How we work

A safe, staged modernization process.

We stabilize and secure before we improve, and we work in small, reviewable steps so the application keeps running for the business throughout.

Codebase assessment

Review the application, its dependencies, framework version, architecture, and known pain points. Identify what is risky, what is salvageable, and what is genuinely broken.

Modernize-vs-rebuild recommendation

Give a clear, honest recommendation on whether to modernize in place or rebuild, based on the state of the code, business goals, budget, timeline, and risk.

Stabilize and secure first

Before adding anything new, get the application onto supported PHP and dependency versions, close obvious security gaps, and get it building and deploying reliably.

Add a safety net of tests

Introduce automated tests around the critical paths so future changes can be made with confidence instead of guesswork.

Framework upgrades & migration

Upgrade Laravel version by version, or plan and execute a migration from legacy PHP into a modern Laravel structure, in safe and reviewable steps.

Refactor & clean up architecture

Untangle the parts of the codebase that slow everything down: duplicated logic, fragile data access, and structure that fights the framework.

Performance & reliability

Address the slow queries, N+1 problems, and resource issues that have built up as the application has grown.

Handover or ongoing support

Hand back a documented, deployable application, or keep it moving forward with a long-term maintenance and development retainer.

Technology

Modernized onto a current, maintainable stack.

We bring legacy applications onto supported, well-understood technology, the same stack we use for new builds, so the system stays maintainable long after the work is done.

  • PHP 8.x
  • Laravel
  • Vue.js
  • Inertia.js
  • Tailwind CSS
  • MySQL / MariaDB
  • Pest / PHPUnit
  • Composer
  • Git
  • CI pipelines
  • Docker
  • Laravel Forge

Modernize vs rebuild

Not every legacy app should be rebuilt.

A rebuild is sometimes the right call, but it is expensive and disruptive, and it is often unnecessary. We give an honest assessment of whether your application is better modernized in place or replaced, based on the state of the code, your goals, budget, timeline, and risk.

Modernize in place

Best when

  • The application still fits the business and has real value.
  • The core architecture is sound, even if it needs cleanup.
  • A rebuild would be expensive, risky, or disruptive to operations.
  • The main issues are version age, security, performance, or test coverage.

Rebuild

Best when

  • The architecture works against the business and against the framework.
  • Technical debt has compounded past the point where fixing is cheaper than replacing.
  • The data model no longer reflects how the business actually operates.
  • Every change is slow and risky no matter how carefully it is made.

Common questions

Questions about modernization.

Can you take over a PHP or Laravel application that another developer built?

Yes. Taking over inherited and abandoned Laravel and PHP codebases is one of our core specialties. We start by assessing the application, then stabilize it, document it, and bring it to a state where it can be safely maintained and extended.

How do you decide whether to modernize an existing app or rebuild it from scratch?

We assess the codebase, architecture, framework version, data model, and business goals first, then give an honest recommendation. We modernize in place when the application still fits the business and the core is sound, and we rebuild only when the architecture or technical debt makes fixing more expensive and risky than replacing.

Our app is on a very old version of PHP or Laravel. Can you upgrade it?

Yes. We handle PHP version upgrades and step-by-step Laravel upgrades, as well as full migrations from legacy or custom PHP frameworks into a modern Laravel structure. We do this in safe, reviewable stages so the application keeps working throughout.

The application has no tests. Is that a problem?

It is common with legacy systems, and it is one of the first things we address. We add automated tests around the critical paths before making larger changes, so upgrades and refactors can be done with confidence instead of guesswork.

Do you offer ongoing support after the modernization work is done?

Yes. Many clients continue with a monthly maintenance and development retainer once their application is stable, so the same studio that modernized it keeps it secure, up to date, and moving forward.

Have an aging PHP or Laravel app you depend on?

If your application is stuck on an old version, hard to change, or inherited from a developer who's no longer around, we can assess it and lay out an honest path to get it stable, secure, and maintainable again.
