Upgrade Umbraco with a clear path to better security, faster performance, and long-term support
Upgrade to a supported Umbraco version to reduce security risk, improve site performance, and give your team a clear path to modern features.
Talk to Our Team
If your organization is running Umbraco 7, 8, or an older version 10 build, your CMS is no longer supported. That means no security patches, no compatibility with modern .NET, and no access to the headless Content Delivery API.
ProWorks has guided organizations through dozens of Umbraco upgrades, from minor version bumps to full platform migrations across major versions. The case for upgrading is clear, and the path forward is well-established.
By the Numbers
What a Modern Umbraco Version Delivers
Active Security Patching
Supported versions receive regular security updates and patches. Running end-of-life software leaves your organization exposed to known vulnerabilities.
Latest .NET Performance
Current Umbraco runs on the latest LTS .NET runtime. Expect faster page loads, reduced memory usage, and significantly improved throughput compared to legacy .NET Framework builds.
Content Delivery API
Umbraco 13 and later includes a built-in Content Delivery API. Power React, Next.js, mobile frontends, or external integrations from a single content repository, with no additional licensing required.
Rebuilt Back Office
Umbraco 14 introduced a completely rebuilt editorial interface based on web components. It loads faster, meets modern accessibility standards, and is designed for real editorial workflows.
Umbraco Cloud Ready
Modern Umbraco versions are fully supported on Umbraco Cloud with Git-based deployments, automated upgrades, staging environments, and built-in team collaboration tools.
AI Ready
Umbraco 17+ give access to Umbraco in AI through the Umbraco MCP Server. In addition, the Umbraco.AI framework makes it easy to add AI enhancements to Umbraco like the ProWorks Page Evaluator

We deploy to production, validate everything, and provide post-launch monitoring so your team moves forward with confidence.
Common Questions About Umbraco Upgrades
Umbraco v13 and v17 are the current long-term support versions. Umbraco v18 is the latest release. Versions 7-12 are end of life and receive no further patches or updates.
Disruption depends on the level of customization and the version gap. ProWorks structures upgrades to minimize downtime using staging environments, phased deployments, and thorough testing before changes go live.
For major version jumps, ProWorks typically upgrades in stages (for example, v8 to v10 to v13) to reduce risk and ensure compatibility at each step. In some cases a direct path is viable.
APIs change between major versions. Our pre-upgrade audit identifies all breaking changes, and we update or replace affected code before any work is deployed to production.
Straightforward upgrades can be completed in 2 to 4 weeks. Complex enterprise sites with significant customization typically take 8 to 12 weeks depending on scope and integration requirements.
