The next Umbraco LTS is here — are you ready?

Umbraco 17 LTS brings the platform in line with .NET 10, setting you up for a long, stable support window. If you’re currently on v13 you’re well-placed; if you’re somewhere else between 7–16, we’ll map the safest path to v17 to get you upgraded as quickly as possible.

Why you should upgrade

As the previous LTS version is replaced, if you do nothing, in future your site could face security risks, compatibility issues, and increased maintenance costs. Upgrading now to Umbraco 17 gives you a faster, more reliable platform built on .NET 10 - ensuring your website stays stable and future-ready.

What makes Umbraco 17 the most powerful release yet?
  • Built on .NET 10 - Faster, more efficient, and future-ready foundation.
  • Performance Boost – Quicker load times and smoother content editing.
  • Security Enhancements – Updated architecture and supported dependencies.
  • Improved Developer Experience – Better APIs, cross-platform tooling, and simplified workflows.
  • Cleaner Codebase – Easier maintenance and scalability.
  • Long-Term Support (LTS) – Stay compliant and supported by Umbraco HQ.
What happens if you stay on older versions?
  • End of support - Older Umbraco and .NET versions will no longer receive security patches.
  • Technical debt - Harder to maintain, slower performance, and potential plugin incompatibility.
  • Integration issues - Modern APIs and tools may stop working.
  • Higher long-term costs - Fixing or rebuilding later can cost more than upgrading now.

Got some questions?

Which Umbraco versions do you upgrade?

We upgrade from v7 to v16 and are actively preparing sites for Umbraco 17 (LTS).

I’m on Umbraco 13 (LTS). Should I move to 17?

Yes - v17 is the next LTS, bringing performance gains and a fresh support window. We plan a clean, low-risk path from 13 to 17.

What’s new that editors will notice?

Cleaner RTE and calmer backoffice (from v16 onward), consistent date/UTC handling (v17), plus quality-of-life tweaks that speed up publishing.

Will there be downtime?

We upgrade in a staging environment and schedule releases to avoid downtime wherever possible.

How long does an upgrade take?

Simple sites: 1–2 weeks. Complex/multisite or heavily integrated builds: we run a short upgrade audit to confirm timelines.

What happens to my content and media?

Everything is migrated and verified - content, media, users, languages, and URLs. We keep redirects and SEO signals intact.

We use custom code and packages (e.g. Forms, custom data types). Is that a problem?

We review your packages and custom code, replace deprecated APIs, and test editors’ workflows. We’ll propose alternatives if a package isn’t compatible.

Can you move us to Umbraco Cloud at the same time?

Yes. We can migrate to Umbraco Cloud and enable auto-patching and Deploy for smoother future updates.

Are we covered if we’re on Digital Wonderlab’s managed service?

Yes. Managed clients are upgraded as part of the service; we’ll contact you to schedule your 17 upgrade.

How much will it cost?

Cost depends on complexity. After a quick upgrade audit, we give you a fixed plan and price before any work starts.

Do you have a rollback plan?

Yes - each upgrade includes backups, version control, and rollback so we can revert safely if needed (we rarely need to).

Still unsure?

Lets talk. We've help hundreds of organisations keep their Umbraco sites up to date.
