SYS.DÉTAIL

PRÉSENTATION

Legacy technology holds your business back. Slow page loads, security vulnerabilities, limited mobile experience, and mounting maintenance costs are symptoms of an outdated tech stack. Our legacy modernisation service moves your website from old technology to a modern, maintainable, and performant architecture without disrupting your business.

We have migrated websites from WordPress, Drupal, Joomla, custom PHP, jQuery-based sites, and Angular 1.x applications to modern React and Next.js architectures. Each migration follows a proven methodology that preserves your SEO rankings, maintains URL structures, and ensures zero downtime during the transition.

The modernisation process starts with a thorough audit of your existing system. We document every page, URL, redirect, form, integration, and piece of custom functionality. This creates a complete migration checklist that ensures nothing is lost in translation. We identify which features should be rebuilt, which can be simplified, and which are no longer needed.

Our migration approach is incremental when possible. Using the strangler fig pattern, we can replace sections of your old site one at a time while both systems run in parallel. This reduces risk and allows you to see improvements immediately rather than waiting for a complete rebuild. Critical features like contact forms and e-commerce functionality are migrated first.

SEO preservation is a primary concern throughout the migration. We create comprehensive redirect maps, migrate all metadata, preserve internal linking structures, and submit updated sitemaps to Google. We monitor Search Console throughout the migration to catch and fix any indexation issues quickly. Our clients typically see SEO improvements after migration due to better performance and cleaner markup.

The end result is a modern, fast, secure website that costs less to maintain and is easier to extend with new features. You get full source code ownership, comprehensive documentation, and a development environment that makes future changes straightforward. Most legacy modernisation projects show a 40-60% reduction in ongoing maintenance costs within the first year.
