Legacy systems maintenance and migrations
We take over, secure, and modernise the systems you already run
Over sixteen years we have inherited and kept running a great many systems we did not originally build — often poorly documented, sometimes years out of date. We make that handover painless: we reverse-engineer how a system really works, document it, and take responsibility for keeping it healthy.
Whether you need a safety net for a critical platform or a long-term partner to own day-to-day operations, we keep your systems available, patched, and ready for what comes next — so your team can focus on the business, not on firefighting.
- Node.js
- PHP
- WordPress
- Drupal
- Symfony
- jQuery
- Vue.js
- PostgreSQL
- MySQL / MariaDB
- Linux
- Nginx
- Docker
How we keep your systems healthy:
-
Inheritance and knowledge transfer
We audit and document undocumented or legacy systems, mapping dependencies and risks so nothing lives only in one person's head.
-
Ongoing maintenance and support
Bug fixes, dependency and security updates, and SLA-backed support with clear response times and incident handling.
-
Patching and dependency upgrades
We bring outdated libraries and frameworks up to date and close known vulnerabilities (CVEs) before they become incidents.
-
Performance and cost optimisation
We profile slow systems, fix bottlenecks, and right-size hosting so platforms run faster and cost less to operate.
-
Backups and disaster recovery
Automated, tested backups and recovery procedures, so a bad day never turns into lost data.
When a system has outgrown its original technology, we move it forward without disrupting the business. We have migrated countless projects to newer stacks, re-platformed them to the cloud, and rebuilt ageing components in modern technologies such as Node.js — improving reliability and developer velocity along the way.
We favour a gradual, low-risk approach over risky big-bang rewrites: stand up the new alongside the old, migrate piece by piece, and verify at every step.
What a modernisation looks like:
-
Technology migration
Re-platforming legacy applications to modern, well-supported stacks — Node.js/TypeScript or the latest Drupal — with data migrated cleanly and integrity verified. That includes the hard upgrades: moving off end-of-life versions like Drupal 7 that can't simply be updated in place.
-
Cloud and containerisation
Moving on-premise or ageing hosting to the cloud, containerised with Docker for predictable, repeatable deployments.
-
Incremental refactoring
A strangler-fig approach that replaces a system component by component, keeping it live and stable throughout.
-
Pragmatic, not dogmatic
Modern isn't always better. We've inherited over-engineered setups — such as a headless WordPress driven by a separate Vue.js front end — and, where the complexity wasn't earning its keep, consolidated them back to a clean, maintainable WordPress. We recommend the architecture that fits your team and budget, not the trendiest one.
-
CI/CD and automation
We add automated build, test, and deploy pipelines so future changes ship quickly and safely.
-
Compliance and accessibility retrofits
Bringing older platforms up to current GDPR and WCAG accessibility standards as part of the modernisation.
Taking over a system means standing behind it. Before and after every change, we make sure it is secure and that it actually works — and we keep watching it in production so problems surface before your users do.
How we keep it trustworthy:
-
Penetration testing and security audits
We probe applications and infrastructure for vulnerabilities and fix what we find, hardening the system against real-world attacks.
-
End-to-end testing
Automated E2E test suites that prove critical user journeys keep working — so refactors and migrations ship with confidence, not crossed fingers.
-
Domain and server monitoring
Uptime, SSL certificate, and domain-expiry monitoring with alerting, so renewals and outages never take you by surprise.
-
Observability and alerting
Centralised logging, metrics, and dashboards that make a system's health visible at a glance and page us when something is wrong.
-
Incident response
Clear escalation paths and on-call support to investigate, contain, and resolve issues fast when they do occur.
