Written Roadmap Delivered
Within 48hrs of the call you receive a written summary: migration complexity rating, indicative timeline, phased approach, and recommended next steps. Yours to keep.
What 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.
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.
Running unsupported CMS can breach GDPR, PCI-DSS, SOC 2 requirements, and invalidate cyber insurance policies that require supported software in your stack.
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.
Agencies completing the best planned migrations are already booking 2025–2026. Waiting until mid-2026 means rushed scope, emergency timelines, and inflated costs — 40–60% price premiums on rush migrations.
Modern hybrid-headless DXP. Evergreen monthly updates. AI-powered content tools. Advanced personalisation. SaaS hosting on Azure. Risk reduction AND a platform upgrade.
SaaS licensing eliminates infrastructure management, automates deployments, and ends disruptive major upgrades. Most clients see IT overhead drop within year one of XbyK.
