In the fast-paced digital world, staying up to date with your website’s underlying platform isn’t just a technical recommendation—it’s a business necessity. If your site is powered by Umbraco CMS, it’s essential to be aware of End-of-Life (EOL) timelines for each version to ensure your site remains secure, supported, and future-proof.
What Does End-of-Life Mean?
When an Umbraco version reaches its EOL, it no longer receives updates—this includes:
- Security patches
- Bug fixes
- Official technical support from Umbraco HQ
That means if vulnerabilities are discovered after the EOL date, your site may become exposed to potential security threats with no official fix or support available.
The Risks of Running an Unsupported Version
Sticking with an out-of-date Umbraco version may seem harmless—after all, your website still works, right? But here’s what you’re risking:
- Security Vulnerabilities
Older CMS versions are prime targets for cyberattacks. Once support ends, any newly discovered vulnerabilities are not patched, leaving your site at higher risk of exploitation.
- Compliance Issues
With GDPR and UK PECR regulations, you have a legal responsibility to safeguard user data. Running unsupported software could put your compliance at risk.
- Performance and Compatibility
As browsers, devices, and integrations evolve, older versions of Umbraco can start to lag in performance or break compatibility with newer technologies.
- Missed Features
Each new Umbraco release comes with performance improvements, updated back-office features, and developer tools that make content management easier and faster.
Key EOL Dates to Know
Here are some critical dates for commonly used Umbraco versions:
- Umbraco 8
- Final Release: 8.18 Feb 2022
- End-of-Life: 24 Feb 2025
- Umbraco 10
- Final Release: LTS Jun 2022
- End-of-Life: 16 Jun 2025
- Umbraco 13
- Final Release: LTS Dec 2023
- End-of-Life: Dec 2026
To avoid falling out of support, it's advisable to upgrade well before the EOL date to allow time for testing and implementation.
Why You Should Upgrade to a Supported LTS Version
Long-Term Support (LTS) versions like Umbraco 13/17 offer:
- Three years of bug fixes
- Six months of security-only updates
- A clear, stable foundation for the future
By upgrading to an LTS version, you can minimise disruption, extend your site’s lifespan, and ensure long-term stability.
How to Plan Your Upgrade
Upgrading Umbraco can range from a simple lift-and-shift to a more in-depth rebuild—depending on your current setup and customisations. Here's how to get started:
- Audit your current site
Understand your dependencies, integrations, and custom code.
- Choose the right upgrade path
For example, Umbraco 8 must be rebuilt on Umbraco 10 or later due to .NET Core differences.
- Test before going live
Ensure everything—from content to third-party services—works smoothly in staging.
