CRAFTED LABS - UPGRADING YOUR UMBRACO WEBSITE

Umbraco End of Life. 

With Umbraco CMS, there are two phases for its major releases, the Support Phase and the Security Phase.   

In the Support Phase, Umbraco will fix bugs, regressions, and security issues, and after this phase ends, the release will go into a Security phase where Umbraco will only fix security issues and will no longer work on patch updates or bug fixes.  

At the end of the Security phase, Umbraco versions are considered End of Life (EOL). This is the last stage in the version’s lifecycle and means that support is no longer given at all.  

Technically, you can still use Umbraco after the EOL date, but if you decide to continue using a major that has reached EOL, there are a number of issues that you might face. These include: 

It’s important to note that once a version of Umbraco reaches its EOL, they’ll also no longer recommend using it and as such, you’ll need to think about upgrading to a newer version.  

Depending on the version that you’re on, this can sometimes be a pretty straightforward process, but for others, it’s a little more difficult.  

So, let’s look at some of the most important versions that have either reached their EOL or will be reaching it soon. 

End of Life versions. 

What is the End of Life plan for current Umbraco releases? 

For the other active releases of Umbraco, here’s the plan for when each will enter the support phase, when they’ll enter the security phase, and when they’ll reach their EOL.  

For anyone using Umbraco 8, 10, 14 or 15, they reached EOL in 2025. If you're using any of these versions, you'll need to upgrade your website to a newer version.
