Umbraco 10 End of Life: What It Means for Your Website

If your website is still running on Umbraco 10, it’s time to start planning your next steps. On 16th June 2025, Umbraco 10 will officially reach its End of Life (EOL). This means there will be no more updates, bug fixes or security patches. While your website will continue to function, running an outdated version comes with risks that could impact your business operations, website performance and security.

Why Does Umbraco 10’s End of Life Matter?
Every Umbraco version follows a defined support lifecycle, ensuring that businesses running on the CMS receive security updates, bug fixes and performance improvements for a set period. However, once a version reaches its End of Life, the Umbraco team no longer provides support, leaving your website vulnerable to a range of potential issues.

What Are the Risks of Staying on an Unsupported Version?
Ignoring the Umbraco 10 EOL deadline could lead to several critical challenges, including:

• Security Vulnerabilities – Without regular security patches, your site is at a much higher risk of cyberattacks, including malware, data breaches and hacking attempts. If a security flaw is discovered after EOL, there will be no fixes, leaving your business and customer data exposed.
• No Bug Fixes or Support – Any bugs or issues that arise post-EOL will no longer be addressed by the Umbraco team. Over time, this can lead to broken functionality, making it harder to manage your website effectively.
• Compatibility Issues – Web technologies evolve quickly. An outdated CMS may not be compatible with the latest third-party integrations, APIs or browser updates. This could lead to website errors, slow performance or even broken features that impact user experience.
• Missed New Features – Umbraco continues to introduce new features, improvements and optimisations in newer versions. Sticking with Umbraco 10 means you’ll miss out on enhanced performance, better content management tools and improved scalability.

How to Future-Proof Your Website Before the Deadline
To keep your website secure, functional and performing at its best, you should start preparing for an upgrade well before the 16th June deadline. Moving to a supported Umbraco version ensures ongoing security updates, performance enhancements and access to the latest features.

Here’s what you should do next:

• Assess Your Current Setup – Review your website’s current functionality, integrations and any custom features to understand the scope of your upgrade.
• Plan Your Upgrade Path – Umbraco provides direct upgrade options, but depending on your website’s complexity, you may need to evaluate whether a standard migration or a full rebuild is the best approach.
• Test Before Going Live – Before making the switch, testing the upgraded version in a staging environment ensures that everything works as expected without disrupting your live site.

What should you do next?

A smooth transition requires expertise, especially if your website has custom components. Partnering with an Umbraco Gold Partner, like Cold Banana, ensures the upgrade is handled efficiently with minimal disruption.

If you’re unsure about the best upgrade path or need to assess the impact on your current setup, now is a good time to explore your options. Preparing early will help prevent last-minute issues and ensure a smooth transition.
