We modernise ageing PHP, .NET and desktop applications step by step: assessment, incremental migration to modern stacks and cloud, careful data migration and a cutover your users barely notice.

Whether your system is a PHP 5 web app, a .NET WinForms desktop tool or a database full of stored procedures, we have a path to a modern, supportable platform.
A fixed-scope review of code, architecture, data, security and running costs that ends in a scored modernisation roadmap with options and estimates.

Learn moreWrapping legacy systems in modern APIs so new front ends, mobile apps and partners can use them while the core is replaced.
Learn moreReplacing dated interfaces with responsive, accessible web front ends designed around how your staff actually work.
Learn moreA 15-year-old VB.NET application rebuilt as a .NET 8 web platform on Azure, migrated module by module over nine months.
Rebuilt on Laravel and PostgreSQL with role-based access and audit logging, 1.2 million records migrated and reconciled.
Batch reports moved to a cloud data warehouse with dashboards, cutting month-end close dramatically.
Most modernisation projects fail because they try to replace everything at once. We de-risk the work by shipping in slices that run alongside the old system until each one is proven.
The strangler pattern lets us migrate one capability at a time with the old system still live, so there is never a single risky switch.
We reverse-engineer and document the hidden logic in old code and data before rewriting, then prove parity with automated tests.
Every migrated table is reconciled record by record, and rollback plans are rehearsed before any cutover.
Weekly demos, a shared risk register and training mean your staff and IT team are ready when each module goes live.
Assessment first, then a sequence of small migrations that each deliver value and reduce risk, ending in a cutover that is a non-event for your users.
We move systems from the technologies below on the left to modern, cloud-ready equivalents your team can hire for and support.
A proven process to turn your ideas into powerful digital solutions.
We analyse code, data, dependencies, security and costs and score each module for value and risk.
We sequence the migration, choose the target stack and cloud, and define parity tests and rollback plans.
We rebuild and migrate module by module, running old and new side by side until each is proven.
We switch users, retire the old system and keep the new platform supported and improving.
Answers to the questions we hear most often. Need more detail? Talk to our team.
The assessment answers this per module. Code that is well structured can often be refactored and upgraded in place; tangled or unsupported code is usually cheaper to rebuild. Most projects end up as a mix, sequenced by business value and risk.
No. We use the strangler pattern so the legacy system keeps running while new modules take over one by one. Final cutovers are scheduled, rehearsed and typically completed without downtime.
We migrate data in rehearsals before the real cutover, reconcile record counts, totals and samples against the source, and keep the legacy database read-only as a fallback for an agreed period.
Yes. We routinely take over undocumented systems. We reverse-engineer the behaviour from code, database and user interviews, document it and lock it in with automated tests before changing anything.
A focused assessment takes two to four weeks. Modernising a typical mid-size business application takes six to twelve months in phases, with the first modules live within the first quarter.
