Migrating to Umbraco 17

Ready for the next version?

Umbraco 17 is available. For organizations still operating on older versions such as Umbraco 8, 10, or 13, now is the time to look ahead. By migrating in a timely manner, you can prevent security risks, compatibility issues, and rising maintenance costs. Moreover, you will receive a faster, more stable, and future-proof platform in return. Migrating does not have to be a complicated project. Webwonders keeps the process clear, precise, and hassle-free.

Why upgrade to Umbraco 17?

Umbraco 17 is not a maintenance release, but a major step forward. Upgrading makes sense especially for organizations that want to keep their platform secure, fast, and future-proof.

1. Your platform gets faster
With .NET 10 and a modern runtime, everything responds noticeably smoother. Both the website and the back office benefit from this.

2. New, sustainable architecture
The back office runs on Web Components and a completely renewed technical base. This makes the CMS more stable and better prepared for the upcoming years.

3. Less dependency on packages
More functionality is now standard in the core. This means less maintenance, less risk of conflicts, and easier upgrades in the future.

4. Better aligned with modern development
Umbraco 17 aligns with how teams build today: headless, API-first, flexible, and well-integratable.

5. Ready for the long term
As an LTS release, this is the version that Umbraco will continue to develop in the coming years. You are guaranteed updates, improvements, and extended support.

6. You prevent your platform from falling behind
The longer you stick to older versions, the more complex and expensive later upgrades become. Switching now means maintaining control.

7. Immediate improvement for editors
Faster, clearer, and more consistent. Fewer clicks, more overview, and a back office that works smoothly.

Smart migration: a new foundation and taking all your content with you

Many organisations think they have to choose between building an entirely new site or transferring all their content as is, including old structures. That is not necessary.

Webwonders combines a clean installation on Umbraco 17 with an automated content migration. As a result:

  • You retain all your valuable content

  • Old fields and customisations are converted to modern structures

  • A clear, future-proof content model is created

  • You avoid manually transferring pages or media

  • You don't lose any data

  • Your platform remains tidy and organised

The result: a new CMS where everything is immediately correct.

Our approach: migrating to Umbraco 17

1. Technical scan

We map your entire environment: content structures, customizations, integrations, and dependencies.

2. Clean Umbraco-17 installation

No old code and no risks. We always start fresh, ensuring your platform is stable and future-proof.

3. Refactoring custom work

Custom functionality, integrations, and templates are rebuilt or cleaned up for Umbraco 17 and .NET 10.

4. Smart content migration

All content and media are automatically transferred. We translate old structures into a logical, modern content model.

5. Thorough testing phase

We test functionality, performance, and editorial workflows before anything goes live.

6. Launch with minimal downtime

Usually just a short content freeze. Afterward, everything runs on Umbraco 17, and your team can continue without interruption.
