Introduction

If your enterprise business website is running on Umbraco 13, then, now it’s 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 websites crashes over night after EOL. However, remaining on the same version means not receiving security updates, bug fixes, compatibility improvements, or official support. Starting to plan from now means planning ahead of time with Techxot, according to your own timeline and simultaneously protect, 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, after this Umbraco will no longer maintain this version of Umbraco.

This means not receiving:

• Security updates
• Bug fixes
• Compatibility improvements
• Performance enhancements
• Official product support

Post this running your website, keeping it secure and reliable will be the responsibility of the organization.

Without official ongoing support, security vulnerabilities create high risk, compatibility updates won’t be released, and technical bugs won’t be fixed.

Why Enterprises Should Start Planning Now

The enterprise business website is not just a domain name; they often include custom codes, third-party integrations, workflows, and content structures. This indirectly means a CMS upgrade is not just another software update and needs expertise and careful planning.

Starting early means having time for:

• Auditing codes and integrations
• Evaluate third-party packages
• Validate content
• Do quality assurance
• Align budget and business outcomes

Planning ahead of time lands you in opportunities where you can modernize your solutions in order to improve performance, eliminate technical debt, simplify content models, and adopt the latest Umbraco capabilities.

What Are the Upgrade Options Available for Enterprise

All the enterprise must understand upgrading the next version is not simple, it’s time consuming, and the strategy entirely depends on your current implementation, desired business outcomes and all available resources.

Upgrade To the Latest LTS Release

For most of the businesses the recommended approach is directly upgrading to the latest Long-term Support version that is Umbraco 19

The latest Umbraco version supports:

• Continuous security updates
• Long-term support for product
• Enhanced platform performance
• Better editor experience
• Predictable upgrade path

Consider A Strategic Rebuild

If your business website is full of technical debt due to outdated architectures following a strategic rebuild can offer better value than a direct upgrade.

This rebuild can modernize and improve integration, redesign architectures, enhance performance, and prepare the CMS for future growth.

Use Extended Long-term Support (XLTS)

If your organization fails to upgrade the platform from Umbraco 13 to 18 or the latest Umbraco version before December 14, 2026, the Extended Long-term Support can help in critical security updates.

Remember XLTS is nothing but a temporary solution until you are prepared for your migration journey

How To Prepare for Your Upgrade

Most migration that succeeds begins with planning and not development.

The initial stage is to start by evaluating your current Umbraco implementation to identify customizations, integrations, and third-party packages. This step helps developers decide whether to rebuild or just upgrade for better long-term support and growth.

The next step is to have clearly define business outcomes which improve website performance, strengthen security, improve editor experience and decrease maintenance cost for future.

Finally, starting the project before EOL to make it a significant advantage for your enterprise business.
