Umbraco 8 to 17:
10x Faster, Zero Data Lost

How we migrated a large enterprise website from Umbraco 8 to Umbraco 17 Headless with a full Azure deployment — improving speed, scalability, and editor experience.

Industry: Enterprise / CMSTimeline: 4 MonthsContent: 2,400+ pages migrated

The Challenge

The client was running a large corporate website on Umbraco 8 — an end-of-life version no longer receiving security updates. The site had 2,400+ content pages, custom document types, media library, and complex navigation. Page load times averaged 4.2 seconds. The client wanted to upgrade to Umbraco 17 Headless to enable a modern React front-end and improve performance, but had tried and failed with another agency due to data migration complexity.

Our Solution

We executed a full migration with zero content loss:

  • Audit of all Umbraco 8 document types, templates, macros, and media library
  • Rebuilt all document types in Umbraco 17 with improved content modelling
  • Automated content migration script preserving all content, URLs, and media references
  • New React + Next.js front-end consuming the Umbraco Delivery API
  • Azure App Service + Azure SQL + Azure Blob Storage deployment
  • Azure CDN for global content delivery and edge caching
  • Azure DevOps CI/CD pipeline for automated deployments
  • 301 redirect map for all changed URLs to preserve SEO rankings
