PHP Migration in Leicester
PHP version migrations for Leicester organisations, where the difficulty is proportional to how long the warnings were ignored. Behaviour deprecated in one version becomes an error in a later one, so an application that has been logging notices for years is holding a list of the exact things that will stop working.
Why this comes up
The problem
The error log has been full of deprecation notices for three years, and the upgrade now fails on all of them at once.
What you get
What we deliver
- Deprecation notices collected from the current version and treated as the work list
- Automated tooling applied to the mechanical changes, with the rest scoped
- Extensions checked, since some are removed and others need replacing
- Behavioural changes identified where the same code produces different results
- One version at a time, with the application working at each step
- Deprecations treated as errors afterwards, so the list cannot rebuild

Working in Leicester
East Midlands
Leicester is our home city. We are based here, most of our team lives here, and a good share of our clients are within a half-hour drive — which means site visits, workshops and hardware installs happen in person rather than over a call.
The most common briefs here are ecommerce for the city's textile and food manufacturers, booking systems for its large independent hospitality scene, and stock and logistics integration for distributors along the M1 corridor.

PHP Migration in Leicester — common questions
- Why do deprecations matter so much?
- Because they are advance notice with a deadline. Each one is behaviour that will be removed, and an application logging hundreds of them has been told exactly what will break — which makes them the most useful planning document available.
- Can tooling do the work?
- A substantial share of it. Automated refactoring handles the mechanical transformations reliably, which leaves the genuinely difficult cases — behavioural changes and abandoned extensions — as the part needing judgement rather than effort.
- What is easy to miss?
- Changes where code still runs and does something different. Sorting behaviour, type coercion and comparison semantics have all changed across versions, and these produce wrong results rather than errors — which testing catches only if it covers them.
- How do we avoid repeating this?
- Fail the build on deprecations once you are current. It converts a slow accumulation into an immediate small task, and the next version upgrade becomes routine rather than a project to recover a supported position.
- Do you work with businesses across Leicestershire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout East Midlands, including Leicester and the surrounding Leicestershire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Leicester businesses do you usually work with?
- The most common briefs here are ecommerce for the city's textile and food manufacturers, booking systems for its large independent hospitality scene, and stock and logistics integration for distributors along the M1 corridor. Beyond that we work across Manufacturing, Textiles & Fashion, Logistics, Food & Drink, Retail and Higher Education.
- Do you cover the areas around Leicester?
- Yes — we work throughout East Midlands, including Loughborough, Nottingham, Derby, Coventry, Northampton. Leicester is an urban area of roughly 560,000+, and we take on work across the wider Leicestershire region rather than the city boundary alone.
