PHP platform migration & modernization
Every month your legacy PHP code costs you more. We migrate it before it becomes a risk - incrementally, with your system running throughout, first results in 4–6 weeks - onto a codebase your team can finally use modern AI tooling on.
The situation
Nothing is on fire, so nothing gets decided. But most teams running an aging PHP platform recognize several of these at once - and they compound.
Is this your platform?
Each is end-of-life, effectively unsupported, or has no viable upgrade path on modern PHP. Find yours and you already know why the last few years have felt harder than they should.
Not on the list? Most of what we migrate is custom - applications written in-house over ten or fifteen years that were never a product at all. The platform matters less than the condition it's in.
The cost of standing still
There's no outage and no crisis, which is why it stays on the agenda for years without moving. Meanwhile, four things get worse every quarter.
Revenue
Every feature costs more than the last. Competitors on newer systems ship in the time it takes you to scope.
Deals
Enterprise buyers, insurers, and acquirers ask about your stack. "It's old but it works" is no longer an acceptable answer.
People
The knowledge lives in a small number of heads. When one leaves, the size of the problem changes overnight.
Margin
Maintenance absorbs budget meant for growth, and the share going to keeping the lights on only climbs.
Why this is a 'sooner' decision, not a 'later' one
Teams using agents like Claude Code have changed what a normal delivery pace looks like. The gains are real, and they land almost entirely on code that is modern, tested, and conventional. Point the same tools at a fifteen-year-old system and you get very little, or you get risk.
The distance between you and a competitor on a modern stack used to grow slowly. Since agents became standard tooling, it grows faster: they get a multiplier on every engineer and you don't. Nothing about your system got worse. The benchmark moved.
Much of a migration is mechanical: translating patterns, writing tests that were never written, documenting what nobody documented. We use AI tools to scan large codebases quickly, find outdated code, and summarise business logic. If you shelved this in 2023 because of the quote, the quote has changed.
For most established companies it isn't a model or a vendor. It's that the core system can't support one: no API surface to connect to, no test coverage to make changes safe, no documentation for an agent to read. Migration isn't a detour from your AI strategy; for many businesses it is the first phase of it.
The fastest way to ship a serious incident in 2026 is to let AI tools loose on a system with no tests, no review gates, and no reliable way to roll back. Teams under pressure to "use AI" are doing exactly that. Migrating puts the guardrails in before the pressure does the damage.
The cheapest AI strategy most established businesses can buy is a codebase their tools can actually read.
Our approach
We use incremental migration strategies that keep your system running while improving it step by step. Full rewrites are the reason this work has a bad reputation: they take years, deliver nothing until the end, and fail in public.
STEP 1
We identify the risks, bottlenecks, and hidden costs in what you're running and put a number on them.
STEP 2
A prioritised modernization plan. Our consultants work alongside your developers to map the real scope of your business logic.
STEP 3
We upgrade your system in phases, without downtime.
First results in 4–6 weeksSTEP 4
Performance, maintainability and future flexibility, plus the tests and documentation that make AI tooling productive on it.
A typical outcome
Before migration
After migration
Modern tooling and a streamlined architecture reduce friction, so teams ship quicker and iterate with confidence.
Cleaner code and current dependencies cut technical debt and the time spent on fixes and upkeep.
Modern frameworks, testing practices, and predictable deployments mean fewer production incidents.
Up-to-date libraries and current practice eliminate known vulnerabilities and strengthen your posture.
Straight answers
These are the three objections we hear on nearly every first call. We'd rather answer them here than pretend they don't come up.
"It still works. Why change?"
You're not choosing between change and stability. You're choosing when the change happens and who controls it. Migrate now and you get a platform worth building on for the next ten to twenty years. Old architectures don't cut it any more, and the gap widens every quarter.
"Migration sounds risky."
It is, done the usual way. Our strategies minimise risk and downtime precisely because we don't do full reconstructions: you get results from incremental rewrites, in phases, with the system live throughout. Each phase leaves you in a working, deployable state.
"There's no time for this."
There rarely is, until there suddenly is: a failed audit, a lost deal, a resignation. Making time before that point is the cheapest version of this decision. And because your team keeps shipping throughout, it costs less of their time than you're assuming.
How we work
Migration projects have a reputation for overrunning. We structure engagements so the worst case is a small, contained loss, not a stalled programme.
Fixed price, defined deliverable, phase by phase. Stop after phase one if you want to, and keep everything delivered so far.
Code, documentation, and infrastructure are yours from day one, in your repositories and your accounts. No proprietary layer you keep paying us for.
Your team continues shipping to customers throughout. We don't ask businesses to pause product development for six months, because most of them can't.
Our engineers work with Claude Code and equivalent tooling under human review. That shows up in your fixed price and your timeline, not quietly in our margin.
You know who is on your project and you talk to them directly. Team changes are agreed with you, not announced to you.
Every engagement ends with documentation and working sessions so your team can carry it, including how to run agent tooling safely on it.

Before you ask
AI tools are genuinely pivotal in modernising legacy PHP, and we use them daily - to scan large codebases quickly, find outdated code, and summarise business logic. What they don't do is make the final decision.
A fifteen-year-old codebase has business rules in it that nobody wrote down and no tool can infer. An experienced engineer is better at reviewing changes, understanding technical context, and making sure an update is safe for production. AI changed the cost and the timeline, not the need for judgement - and the projects we get called in to rescue are usually the ones that skipped that part.
It depends on the size and complexity of the application, and anyone who quotes you before seeing the code is guessing. The first step is a fixed-fee audit of your codebase; from those results we can estimate the migration properly.
What we will say up front: these programmes cost meaningfully less to deliver than they did three years ago. If you priced this in 2022 or 2023 and shelved it, that number is out of date.
Simple applications can be migrated in weeks; more complex codebases take months. We favour progressive migration because full rewrites are riskier, but we don't rule anything out - the choice is made on the project's details, not on principle. In either case you should expect the first visible results in four to six weeks.
No. That's the single most common reason these projects never start, so we designed around it. Your team keeps shipping on the current system while the new one is built beside it and takes over gradually.
Rarely because your team can't - usually because they're already fully committed to keeping the current system running, and this work competes directly with that. We're often brought in so the internal team doesn't have to choose.
The other reason is pattern recognition. Our engineers have worked with PHP for decades. They built on the architectures that later became difficult to work with, then migrated away from them. They know the downsides of the old ways and the strengths of the new ones because they've lived on both sides.
Legacy applications get harder to maintain, less secure, and less efficient every year, and the cost shows up as slower delivery and harder hiring long before it shows up as an incident. A modern architecture improves code quality and performance, and current PHP frameworks have proven to be a better foundation to build on.
We've written about this at length - see why up-to-date PHP versions matter.
You can, at the end of any phase. Each phase leaves the system in a working, deployable state, never half-migrated. You keep the code and the documentation regardless.
