With the right planning and an experienced migration partner, your transition to Xperience by Kentico can become a catalyst for innovation, improved performance, stronger security, and scalable growth.
Yes. Organizations should begin planning their migration well in advance to avoid the risks associated with unsupported software, including security vulnerabilities and compatibility challenges.
The duration depends on the size and complexity of the implementation. Small websites may take a few months, while enterprise environments with multiple sites, custom modules, and integrations often require six months or longer.
Not always. Many custom components require redevelopment or modernization to align with the architecture of Xperience by Kentico. A technical assessment is recommended before starting the project.
A well-planned migration should preserve SEO performance. Maintaining URL structures, implementing proper redirects, retaining metadata, and validating technical SEO before launch are essential best practices.
Delaying increases exposure to security vulnerabilities, unsupported software, rising maintenance costs, compliance issues, and reduced compatibility with modern technologies. Planning early gives organizations greater control over timelines, budgets, and business continuity.
If your organization is preparing for the Kentico 13 End-of-Support, now is the ideal time to assess your environment, identify migration challenges, and build a roadmap tailored to your business goals. A structured approach backed by Kentico experts can help ensure a secure, efficient, and future-ready migration with minimal disruption.
