Read part one of our Kentico series: What is Xperience by Kentico?
What Xperience by Kentico means for you
Websites built on Kentico 13
Kentico 13 is currently in its extended support phase, which Kentico has committed to maintaining until the end of 2026. That means you're still supported, but it's worth starting to plan ahead.
That being said, refreshes and hotfixes will stop by the end of 2025. For businesses or local governments with compliance requirements or plans for future digital transformation, this may become a consideration sooner rather than later.
In short, the introduction of Xperience by Kentico is not a red flag for your Kentico 13 website right now, but it is a reminder to start planning for the future.
Websites built on an earlier version of Kentico
All websites built on earlier versions of Kentico are no longer supported. Having an unsupported Kentico website could be a major liability for both your site and your users. If you’re in this position, you should consider migrating to Xperience by Kentico as soon as you can.
End-of-life: The problem with an unsupported CMS
When your CMS reaches end-of-life, it doesn’t stop working overnight, but the risks multiply quickly:
- Security vulnerabilities: Without security updates, your platform becomes an easy target.
- Compliance issues: Unsupported software can put you at odds with data protection standards.
- Technical debt: The older your tech stack, the more time your developers spend maintaining it instead of innovating.
- Compatibility challenges: New browsers, APIs, and third-party integrations evolve while your CMS doesn’t.
Relying on unsupported software can result in higher costs and lost opportunities in the long run. It’s the digital equivalent of putting off home maintenance until the ceiling starts leaking.
What sets Xperience by Kentico apart
All of that being said, the reasons to switch to Xperience by Kentico go far beyond ticking compliance boxes.
