Why You Should Plan Your Upgrade Now

Umbraco 13 reaches End of Life on 14 December 2026. Upgrades done properly take planning, scoping, and time - leave it too late and you're rushing, cutting corners, or paying over the odds.

Umbraco 17 is built on .NET 10 LTS - a modern, supported stack built for the long haul. Here's what you get:

  • Long-term security patches and performance updates
  • A faster back office — AngularJS out, modern web components in
  • Load balancing for large content teams
  • Stronger headless capabilities (RESTful and GraphQL APIs)
  • Enhanced .NET 10 security
  • A new text editor for faster content editing
  • Multilingual block-level translation

The question isn't whether to upgrade. It's who you trust to do it properly.

Benefits of Umbraco
Upgrade from Spinbox

Umbraco rebuilt it's entire back office from the version 14 onwards, meaning custom editors, dashboards, or workflows will need rebuilding, not just migrating. As Umbraco Gold Partners, we know exactly where the pitfalls are. Every project starts with a free review, a clear scope, and a plan your whole team can follow. Here's how we do it:

Assess:

Before a single line of code is touched, we get under the bonnet of your existing Umbraco environment — reviewing your version, hosting, packages, integrations, and content complexity.

We score the technical risk and agree the safest path to Umbraco 17. You'll have a signed project plan before anything begins.

Build: 

Your live site stays live throughout. We clone your environment into a dedicated staging setup, rebuild any custom back office functionality to the new Extension API standards, and run thorough smoke, regression, and data integrity tests.

Nothing moves forward without sign-off.

Improve:

We don't just make it work — we make it better.

Legacy editors are migrated to modern blocks, permissions and workflows refined, and new features properly configured. You end up with an Umbraco build that's not just current, but genuinely nicer to work with day to day.

Launch:

We schedule a controlled deployment with rollback options in place, monitor performance closely post go-live, and stay close to support both your IT team and content editors through the bedding-in period.

You won't be left to figure it out alone.
