Umbraco 13 is the most solid version prepared to face current challenges in web development and digital experience. It offers long-term support (LTS), optimized performance over .NET 8 and an architecture ready for multichannel integrations, all with much more flexible content management.

By remaining in previous editions, your organization renounces improvements that are already standard in many digital projects.

The following summarizes the Umbraco 13 key benefits and everything you're missing out on if you haven't upgraded yet.

Risks of remaining in previous versions

Using older versions of Umbraco involves working with a technology that no longer evolves or receives support. This means greater exposure to vulnerabilities, difficulties integrating new tools, more work for development teams, and a less efficient editorial experience.

In addition, the longer the upgrade is delayed, the more complex the migration will be. This is so impactful from the point of view of IT and tool administration, as from the web editor experience, which continues to operate in a more rigid and less intuitive environment.

In an environment where agility, security and scalability are a priority, sticking with an obsolete version represents a barrier to digital growth.

Comparison of LTS versions

Umbraco publishes LTS (Long-Term Support) versions with extended support cycles, designed for projects that require stability, security and continuity in the medium and long term.

In this table we compare the most relevant LTS versions. This comparison will help you make informed decisions based on where your platform is.

Umbraco 7 ❌No support, no modular design, no modern APIs. ⚠️Website vulnerable since 2023, no patches or future compatibility.
Umbraco 10 ❌Last months of support, limited features. ⚠️Support ends June 2025, higher maintenance cost and more complex future migration.
Umbraco 13 ✅Updated technology, improved performance, flexible editing. ✅No risk: stable, secure version ready to scale. LTS support until 2026.

  • Reduction of accumulated technical debt.
  • Updated architecture on .NET 8.

What a CMO earns

From marketing, the editing experience and responsiveness improve considerably.

  • More visual, flexible and autonomous editing system.
  • Less dependence on the technical team to launch content or campaigns.
  • Better multichannel management from a single platform.
  • Increased speed of execution and adaptation to new initiatives.

What a CFO earns

In financial terms, upgrading allows for better control of costs and avoids larger investments in the future.

Not upgrading is also a decision

Not upgrading means taking on more risks, spending more time resolving limitations, and losing opportunities for improvement in performance, security and operational agility.
