Book Free AssessmentWhat staying on Kentico 13
actually costs you
Your site won't switch off on January 1, 2027 — but here's the real cost of staying on unsupported software, and what DotStark's proven migration process protects you from.
Unpatched Security Gaps
Kentico 13 runs on .NET 6, already EOL since November 2024. Zero-day vulnerabilities discovered after Dec 2026 will stay open permanently. Your site becomes a known target.
Compliance & Insurance Risk
Running unsupported CMS can breach GDPR, PCI-DSS, SOC 2 requirements, and invalidate cyber insurance policies that require supported software in your stack.
Zero Kentico Support
Critical issue at 2am? After Dec 2026, you're on your own. No tickets, no hotfixes, no patches. Your internal team carries 100% of the risk alone.
Last-Minute Cost Spikes
Agencies completing the best planned migrations are already booking 2025–2026. Waiting until mid-2026 means rushed scope, emergency timelines, and inflated costs. We've seen 40–60% price premiums on rush migrations.
XbyK Unlocks Real Growth
Modern hybrid-headless DXP. Evergreen monthly updates. AI-powered content tools. Advanced personalisation. SaaS hosting on Azure. This isn't just risk reduction — it's a platform upgrade.
Lower Long-Term TCO
SaaS licensing eliminates infrastructure management, automates deployments, and ends disruptive major upgrades. Most clients see IT overhead drop significantly within year one of being on XbyK.

Real results from real migrations — not initials, not composites.
DotStark supported us during the complete rebuild of our website on the Xperience by Kentico (XbyK) platform, working alongside our primary development team. The team was highly responsive, communicative, and committed to meeting our project deadlines. They were always available when needed and often went the extra mile, putting in additional hours to ensure progress stayed on track.
We highly recommend DotStark if you are looking to acquire a high-performance solution from an experienced team. This firm has been our trusted partner for all kinds of digital solutions. Their professionalism and dedication to delivering premium-quality solutions are matchless. You must consider it as a go-to firm for any of your future digital projects.
Commendable work! The development team at DotStark provided us with bespoke solutions as per specific requirements. I am very impressed with the way they pay attention to each and every detail and provide quick responses with clear communication. We are looking forward to working with them again for the next project!

No - it is a full replatform, not a click-to-upgrade. Templates, custom modules, and backend code must be completely rebuilt in XbyK's architecture.
Most migrations take 3–6 months from kick-off to go-live. Complex enterprise sites with heavy integrations can take up to 9 months.
Cost varies based on site complexity, number of integrations, and custom development required. Simpler sites cost less; large enterprise builds with e-commerce or complex APIs cost significantly more. An accurate estimate requires a scoping assessment.
After December 31, 2026, no security patches will be issued - leaving your site exposed to unpatched vulnerabilities. In regulated industries, running unsupported software can breach GDPR or PCI-DSS compliance. Delaying migration also increases cost as partner availability tightens closer to the deadline.
Yes — Kentico's official Migration Toolkit transfers your database content and media files from Kentico 13 to Xperience by Kentico. However, templates and custom code are not transferred and must be rebuilt.
Xperience by Kentico (XbyK) is Kentico's modern Digital Experience Platform built on .NET 8+, supporting headless, hybrid, and traditional architectures. It replaces Kentico 13 with continuous SaaS delivery, built-in AI tools, and advanced personalization capabilities.
DotStark begins every migration with a discovery and scoping phase before committing to any timeline or cost estimate. As a certified Kentico Silver Partner, DotStark follows a parallel-environment approach — keeping your live site fully operational throughout the entire migration process. Every project is individually scoped to eliminate surprises at go-live.
DotStark delivers Kentico migrations across healthcare, financial services, higher education, manufacturing, and e-commerce.
XbyK SaaS (hosted on Azure) handles infrastructure, backups, and updates automatically — ideal for teams wanting zero server management. Private cloud gives full hosting control, preferred by healthcare, finance, and other regulated industries.
