We've been the top Kentico partner for years - and have helped more organizations move to Xperience by Kentico than any other partner. Here's our take on moving to XbyK - common questions and things to consider.
Benefits of moving to Xperience by Kentico.
No matter what platform you're currently on, there are many benefits to switching to Xperience by Kentico.
Future-proof your digital experience: Xperience by Kentico is built on the latest .NET and cloud technologies, ensuring long-term security, scalability, and compatibility with modern marketing tools.
Faster, easier management: Gain a unified Digital Experience Platform (DXP) that connects content, marketing automation, and analytics—reducing maintenance and speeding up campaign delivery.
A personalized built-in AI assistant: Exclusive only to Xperience by Kentico - you have the option of a conversational AI search assistant add-on to help take your site’s user experience to the next level.
If your site is on Kentico 13 or an earlier version, it will continue running after support ends, but it will no longer receive security updates, feature enhancements, or compatibility fixes. Operating on an unsupported version increases long-term risk, but there’s a clear path forward. We can help you move into Xperience by Kentico with a secure, low-disruption migration.

Why is Kentico dropping support for Kentico 13 and older?
Kentico is ending support for older versions because those early versions rely on outdated technology that can’t be secured or maintained long-term. Kentico is ending support for Kentico 13 and earlier versions to align with its official product lifecycle and focus resources on the next-generation Xperience by Kentico platform. These older versions rely on outdated technologies like .NET 6, which Microsoft will no longer support, creating security and compatibility risks. By retiring legacy versions, Kentico can deliver stronger performance, cloud readiness, and innovation on its modern platform while ensuring users stay secure and future-ready.
Your site will still run after support ends, but it becomes increasingly insecure, incompatible, and expensive to maintain.
If you choose not to upgrade, your current Kentico Xperience instance will continue to run, but it will no longer receive new security updates, hotfixes, or feature enhancements once your version reaches the end of support. Over time, this creates increasing risks and limitations, including:
Security vulnerabilities: Without ongoing patches, your site becomes more exposed to modern security threats.
Compatibility issues: New browsers, third-party services, .NET updates, and hosting environments may stop working reliably with your older version.
Higher maintenance costs: You'll end up spending more time troubleshooting legacy issues, implementing workarounds, and keeping unsupported code running.
No access to new features: You miss out on improvements in performance, personalization, marketing automation, deployment workflows, and the entirely new .NET architecture in Xperience by Kentico.
Growing upgrade complexity: The longer you wait, the more difficult (and costly) the eventual migration becomes due to increasing technical debt.
In short, not upgrading doesn’t break your site immediately—but it does steadily increase risk, cost, and operational overhead while limiting your ability to evolve your digital experience.
