In short

63Digital builds and upgrades Umbraco sites on .NET. Our own site is built on Umbraco 17 LTS, upgraded directly from Umbraco 13, and we've rebuilt sites like Clarkston Colts' on a clean, fast Umbraco front-end. If you're still on Umbraco 13, which reaches end of life on 14 December 2026, we can plan and run your move to 17.

FAQ

Common questions

When does Umbraco 13 support end?

Umbraco 13 is an LTS release that left active support on 14 December 2025 and reaches end of life on 14 December 2026, after which it gets no security fixes. Umbraco 17 LTS is supported until 27 November 2028.

Can you upgrade Umbraco 13 straight to 17?

Yes. We upgraded our own site directly from 13.13 to 17.4, and the database migrations ran on first boot. Our step-by-step guide covers what to prepare and what broke.

Will my Umbraco packages work on 17?

Only if they have a v17 release. Check every package before you start. On our own upgrade, a theme package without a v17 build held things up until its release shipped.

Still on Umbraco 13?

End of life is 14 December 2026. Tell us about your site and we'll tell you what an upgrade to 17 involves.
