Kentico 13 Support Is Ending. Waiting Is a Risk.
If your organization is still operating on Kentico 13, Kentico 12, or any earlier version, the window to modernize is closing fast - and the cost of inaction is rising.
Kentico Xperience 13 reaches end-of-support on December 31, 2026.
After that date, any organization still on legacy Kentico will be running without vendor support, without security patches, and without bug fixes. Kentico's own lifecycle policy is explicit: continued use after end-of-life is entirely at the customer's risk. No extended support. No safety net.
This is not a simple CMS upgrade. This is a security, compliance, operational continuity, and cost-containment decision.
So, what are the real-world impacts of delaying modernization?
Organizations that postpone Kentico modernization face compounding risks:
→ Exposure to unpatched security vulnerabilities can increase the risk of breaches and compliance failures.
→ Aging .NET Framework / MVC 5 stacks grow progressively more expensive and difficult to maintain over time.
→ Integrations become fragile as martech and SaaS platforms move beyond compatibility with legacy technology.
→ Shrinking developer availability for outdated technologies.
→ Delayed actions force larger, slower, and more expensive migrations when deadlines require immediate action.
The longer teams wait, the more complex and risky the transition becomes.
The Smart Move: Start Planning Now
Modernizing to Xperience by Kentico on ASP.NET Core delivers:
→ Faster performance and improved scalability
→ A future-proof architecture aligned with modern .NET
→ Better long-term support and security posture
→ A cleaner foundation for personalization, automation, and AI-driven digital growth
Kentico's documentation is clear:
Migration requires content and data migration via the Kentico Migration Toolkit, paired with manual rebuilding of code, widgets, and customizations for the new architecture.
This is a real project - not a patch.
