What happens when Umbraco V13 reaches End-of-Life?
Risk grows
From December 2026, V13 will be a security risk and one of the first things an auditor or regulator might flag.
Innovation stops
V17 runs on .NET 10 with a powerful AI layer. It is Agent-Ready and enterprises are already planning their AI roadmaps. After December, V13 will stand still while the V17 users move on.
Choice narrows
Leaving your upgrade close to the deadline gives you less flexibility in choosing your upgrade partner, reducing your control over the outcome.

⚠️
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.
⚠️
Your hosting environment is load-balanced, multi-region, or has bespoke Azure configuration that adds scope to testing.
