The Challenge

Fluke's product documentation and marketing sites were running on Drupal 7, a legacy platform reaching end-of-life. The sites suffered from poor performance (53 Lighthouse score), terrible SEO (46 score), and were difficult to maintain. We needed a modern platform that could deliver fast page loads, excellent SEO, and a better developer experience.

The Solution

I led the migration from Drupal 7 to Astro, a modern static site generator optimized for content-heavy sites. The project required careful content migration, URL mapping to prevent broken links, and performance optimization to maximize the benefits of the new platform.

Key technical achievements:

  • Migrated content and URL structure with minimal 404s (clean cutover)
  • Implemented image optimization and lazy loading strategies
  • Set up Cloudflare RUM (Real User Monitoring) for performance tracking
  • Created redirect mapping for legacy URLs to maintain SEO value
  • Optimized font loading and caching strategies

The Impact

The migration delivered significant improvements across all metrics:

  • Performance: +32% (53 → 70 Lighthouse score)
  • SEO: +100% (46 → 92 Lighthouse score, nearly doubled)
  • Best Practices: 100% (perfect score, up from 92)
  • Accessibility: +8% (87 → 94)
  • Real User Metrics: 91% of page loads achieving "Good" LCP scores (sub-1 second)

Post-launch monitoring revealed minimal 404 errors, with only a handful of legacy URLs needing redirects. The clean cutover demonstrated strong planning and execution, maintaining SEO value while delivering a dramatically faster user experience.

This project proved that strategic platform modernization can deliver immediate, measurable improvements while reducing long-term maintenance burden.
