Umbraco 13 ends in 2026.Upgrade withconfidence

Security patches stop. Compatibility breaks. Umbraco talent gets scarce and expensive. Move to Umbraco 17 with a certified partner who has run this migration dozens of times — on time, on budget, with zero data loss.

Why upgrade now

Umbraco 13 reaches end-of-life in December 2026.

After December 2026, Umbraco 13 receives no security patches, no fixes and no official support. Vulnerabilities stay open, integrations drift out of compatibility, and developers willing to maintain an end-of-life CMS get scarce and expensive. Every month you wait, the migration gets bigger and the risk grows.

Ready for structured growth?

In the last year alone we delivered 130+ Umbraco upgrades — fixed-scope, cost-effective and on time. With Double Shore you get:

Security & full support back, on a modern Umbraco 17.
Faster performance and a better editing experience for your team.
SEO-safe migration — your URLs, content and rankings preserved.
Your integrations migrated and tested, not rebuilt from scratch.
A fixed, predictable price and post-launch support.

Let’s start building together

When we first started working with Double Shore, we had no website, no branding and no real digital presence. We needed a complete solution to help position our business and start attracting customers. Looking back, investing in our brand and digital presence was an important step for our growth, and the support throughout the entire process made a real difference.
