Introduction
If your enterprise business website is running on Umbraco 13, then now is the time to start planning your upgrade. Umbraco 13 will reach End of Life (EOL) on December 14, 2026. After this date, Umbraco 13 will no longer receive further platform version updates from Umbraco HQ.
This doesn't mean your business website will crash overnight after EOL. However, remaining on the same version means you will no longer receive security updates, bug fixes, compatibility improvements, or official support. Starting to plan now gives you time to move according to your own timeline while protecting, improving, and extending your platform for future updates.
What Will Happen When Umbraco 13 Reaches EOL?
Once Umbraco 13 reaches EOL on December 14, 2026, Umbraco will no longer maintain this version.
This means you will no longer receive:
Security updates
Bug fixes
Compatibility improvements
Performance enhancements
Official product support
After EOL, keeping your website secure and reliable will become the responsibility of your organization.
Without official ongoing support, security vulnerabilities can create higher risks, compatibility updates may not be released, and technical bugs may remain unresolved.
Why Enterprises Should Start Planning Now
An enterprise business website is not just a domain name. It often includes custom code, third-party integrations, workflows, and complex content structures. This means a CMS upgrade is not simply another software update and requires expertise and careful planning.
Starting early means having time for:
Auditing code and integrations
Evaluating third-party packages
Validating content
Conducting quality assurance
Aligning the budget with business outcomes
Planning ahead also creates opportunities to modernize your solution, improve performance, eliminate technical debt, simplify content models, and adopt the latest Umbraco capabilities.
What Are the Upgrade Options Available for Enterprises?
Every enterprise should understand that upgrading to the next version is not always simple. It can be time-consuming, and the right strategy depends on your current implementation, desired business outcomes, and available resources.
Upgrade to the Latest LTS Release
For most businesses, upgrading to the latest Long-Term Support version can provide a more sustainable path forward.
The latest Umbraco version supports:
Continuous security updates
Long-term product support
Enhanced platform performance
Better editor experience
A predictable upgrade path
Consider a Strategic Rebuild
If your business website has accumulated significant technical debt because of outdated architecture, a strategic rebuild may offer better long-term value than a direct upgrade.
A rebuild can modernize the platform, improve integrations, redesign architecture, enhance performance, and prepare the CMS for future growth.
Use Extended Long-Term Support (XLTS)
If your organization is unable to upgrade from Umbraco 13 to a supported version before December 14, 2026, Extended Long-Term Support (XLTS) may provide additional time through continued critical security updates.
However, XLTS should be viewed as a temporary solution rather than a replacement for a long-term migration strategy.
How to Prepare for Your Upgrade
Most successful migrations begin with planning rather than development.
The initial stage should involve evaluating your current Umbraco implementation to identify customizations, integrations, and third-party packages. This helps your development team determine whether a direct upgrade or strategic rebuild is the better option.
Next, clearly define your business outcomes. These may include improving website performance, strengthening security, enhancing the editor experience, and reducing maintenance costs.
Finally, starting the project before EOL gives your enterprise a significant advantage. It provides more time to test, resolve issues, coordinate teams, and complete the migration with less disruption.
