Kentico Xperience 13 has been a reliable platform for many organisations since its release in 2020. But as with all technology, evolution is inevitable. Kentico has announced that Xperience 13 will reach its End of Life (EOL) in December 2026, meaning that no further updates, bug fixes, or official support will be provided. While that date may seem distant, the reality is clear: the clock is ticking, and planning your migration now is critical.
In this article, we’ll explore why EOL matters, what risks you face if you delay, and how to create a practical migration roadmap that sets your organisation up for success.
Why EOL Is More Than Just a Date
When a platform reaches EOL, it doesn’t stop working overnight. Your site will still run, but without vendor support, you’re exposed to significant risks:
-
- Security Vulnerabilities: No more patches means any new exploit could compromise your site and data.
- Compliance Challenges: GDPR and other regulations demand secure systems. Running unsupported software can put you at legal risk.
- Integration Breakdowns: As third-party tools evolve, your legacy CMS may struggle to keep up, leading to costly workarounds.
- Rising Maintenance Costs: Keeping an outdated system alive often means higher developer hours and technical debt.
In short, EOL isn’t just a technical milestone, it’s a strategic inflection point.
The Migration Opportunity
Kentico’s next-generation platform, Xperience by Kentico, isn’t just an upgrade, it’s a reimagined digital experience platform built on modern architecture (.NET Core, cloud-ready, API-first).
Key benefits include:
-
- Evergreen Updates: Continuous improvements without disruptive version jumps.
- Cloud-Native Flexibility: Deploy on-premise or in the cloud with container support.
- Headless & Hybrid Delivery: Future-proof your content strategy with API-first capabilities.
- Enhanced Marketing Tools: Personalisation, automation, and AI-driven insights baked in.
Migrating isn’t just about avoiding risk, it’s about unlocking new capabilities that can transform your digital strategy.
How to Plan Your Migration: A Practical Roadmap
1. Audit Your Current Setup
Start by mapping your existing site, including requesting your existing Kentico partner agency’s assistance with this, as they will typically have more detailed knowledge of your current setup:
-
- Page types, templates, and widgets.
- Custom modules and integrations (CRM, ecommerce, analytics).
- Content workflows and SEO-critical elements.
This audit will reveal what can migrate easily and what needs redevelopment.
2. Define Your Scope and Goals
Ask the big questions:
-
- Which features are essential to carry forward?
- What can be retired or reimagined?
- How can we leverage new capabilities like structured content and AI?
Clear objectives prevent scope creep and keep your migration focused.
3. Build Your Timeline
Don’t wait until Q4 2026. A typical migration involves:
-
- Discovery & Planning
- Development & Content Migration
- Testing & Launch
Starting in early 2026 gives you breathing room for unexpected challenges.
4. Use the Right Tools
Kentico provides a Migration Toolkit to transfer content, templates, and assets. However, custom modules and legacy features often require redevelopment. Factor this into your timeline and budget.
5. Test, Train, and Optimise
Before launch:
-
- Run full QA, SEO, accessibility, performance, and security.
- Train your team on new workflows and tools.
- Plan for post-launch optimisation and continuous improvement.
Common Pitfalls to Avoid
-
- Underestimating Complexity: Migration is a replatforming effort, not a simple upgrade.
- Ignoring Integrations: Validate third-party dependencies early.
- Leaving It Too Late: Compressing the timeline increases risk and cost.

Kentico Xperience 13’s EOL isn’t just a deadline, it’s an opportunity. By planning now, you can transition smoothly to a modern, scalable platform that supports your digital ambitions for years to come.
