In short
Why you need to act now
Umbraco 13 was released in December 2023 as an LTS version. Active support ended in December 2025; the final security phase ends on 14 December 2026. After that, no more security updates arrive — a risk to both your security and your compliance.
What changes from 13 to 17
This is not a routine update. Since version 14, Umbraco runs on a completely rebuilt backoffice — which is exactly why it pays to have a specialist handle the leap.
where you are now
- Legacy AngularJS backoffice
- Runs on .NET 8
- Backoffice on a single server
- Support ends 14 Dec 2026
where you're going
- Modern backoffice in TypeScript and Web Components
- Runs on .NET 10 (LTS)
- Backoffice load-balances across servers
- Future-proof until late 2028
