Website Modernization
Rebuilding an ageing website's technical foundations, such as outdated CMS versions, unsupported PHP, jQuery-heavy themes or legacy hosting, onto a secure, fast and maintainable modern stack.
Capability overview
What website modernization involves
Some websites look acceptable but run on foundations that have become risky: CMS versions no longer receiving security updates, unsupported PHP releases, abandoned plugins, custom code nobody understands, fragile hosting and front-end libraries that slow every page. Website modernisation replaces those foundations before they cause incidents.
Modernisation can mean upgrading the existing CMS carefully, rebuilding the theme with modern standards, moving from a legacy CMS to WordPress, Drupal or headless architecture, or adopting static and hybrid rendering with frameworks such as Next.js and Astro. Content and URLs are preserved where valuable, while technical debt is removed.
The goal is a site your team can maintain safely for years, with automated deployments, current dependencies, documented hosting and a clear update routine.

Ask a questionModernisation focuses on technical foundations, security and maintainability. Redesign focuses on structure, content and user experience. Many projects combine both, but they can be done separately.
Yes. Existing designs can be rebuilt on a modern stack, often with small improvements to accessibility and performance.
Known vulnerabilities may remain unpatched, plugins may stop working and hosting providers may eventually remove support, increasing security and downtime risks.
A technical audit is fixed price. The modernisation project is quoted based on templates, custom functionality, content migration and hosting changes.
