What happens when V13 reaches End-of-Life?
Regulatory headaches
After December 2026, V13 becomes a security risk and one of the first things an auditor or regulator might flag.
Innovation stalls
V13 stands still while the Umbraco ecosystem moves on. V17 runs on .NET 10 with a powerful AI layer. Waiting to upgrade makes it harder to catch up and compete.
Choice narrows
Leaving it close to the deadline gives you less flexibility in choosing your upgrade partner, reducing your control over the outcome.
Umbraco V13 reaches end of life: December 2026. After that date, security vulnerabilities are discovered not patched. Your platform becomes a liability, not a tool.
A service where clarity, quality and reputation matters
December is the deadline. Now is the opportunity

*When might the upgrade cost more?
⚠️
Your site uses custom Backoffice extensions. Bespoke dashboards, property editors, or section views built for V13's AngularJS architecture will need updating.
⚠️
You have third-party integrations like CRM, payment, or data feeds that were hand-built for V13 and may need remapping.
⚠️
You're a uSync.Complete user with complex sync configurations that need additional review before migration.
