Don't just upgrade, improve. Discover how moving from Umbraco 13 can unlock better performance, faster iteration, and measurable business impact.
Rich GreenUmbraco 13 (one of the most widely adopted LTS versions) reaches end-of-life (EOL) on 14th December 2026. And while that sounds like a technical milestone, the real story is much bigger.
This isn't about a CMS version. It's about protecting your ability to drive measurable business impact through your website.
Because in today's environment (where acquisition costs are rising and user expectations are higher than ever), your website isn't just a platform. It's your engine for growth.
Don't leave it to the last minute. Talk to our development team about an upgrade plan that improves performance, not just your version number.
Most organisations will approach this as a migration project.
That's a mistake.
Because moments like this are rare opportunities to step back and ask a more valuable question:
Is our website truly working as hard as it should?
Modern platforms, especially newer versions of Umbraco, aren't just more stable; they're also more powerful. They enable:
Faster, more scalable experiences
Better integration with data and personalisation tools
Continuous optimisation, not one-off improvements
In other words, they support what we call intelligent digital experiences, platforms that don't just exist, but adapt, learn, and improve over time.
That's where real growth comes from.
Umbraco 17 changes the role of the CMS. It's no longer just a platform to manage content; it actively helps teams work smarter. With AI built in, you can accelerate development, improve content quality, and remove a lot of the friction that slows teams down today.
Umbraco outlines three clear paths forward. But the right choice depends on your ambition, not just your tech stack.
The most common route.
Keeps you supported and secure
Unlocks new features (including the updated backoffice from v14 onwards)
But if treated as a simple "lift and shift," you risk carrying over the same performance limitations.
A short-term solution.
Extends security coverage by 6, 12, or 24 months
Buys you time to plan properly
But: This delays the problem; it doesn't solve it.
This is where things get more interesting.
Cloud isn't just about easier migrations. It fundamentally changes how you manage and evolve your platform:
Smoother upgrades in the future
Reduced maintenance overhead
Faster deployment and iteration
Better foundation for ongoing optimisation
This aligns closely with how we approach integrated optimisation: building platforms designed to improve continuously, not just launch and sit still.
Upgrading isn't just about staying supported; it's about what your platform enables you to do next.
With Umbraco 17, that shift becomes much more significant.
New capabilities like Umbraco MCP, Umbraco Skills, and Umbraco.AI open the door to a more intelligent way of working across both development and content.
In practice, that means:
Faster development cycles: reducing time spent on repetitive tasks and enabling teams to ship improvements more quickly
Smarter content workflows: with support for tone of voice, structure, and consistency at scale
More efficient teams: doing more with less by combining automation with human expertise
A stronger foundation for personalisation and optimisation: supporting more adaptive, data-driven experiences over time
This upgrade isn't just about adding AI features for the sake of it. It's about removing friction throughout the workflow, from build to optimisation, so your website can evolve faster and deliver greater impact.
Leaving this too late creates pressure. And pressure leads to poor decisions.
Starting early gives you something far more valuable: control.
It allows you to:
Properly assess your current performance (not just your tech)
Align your platform with business goals
Embed CRO, SEO, and data into the rebuild, not bolt them on later
Prioritise what will actually drive commercial outcomes
This is how you create momentum from month one, a core principle in how we deliver value.
We see the same patterns across many sectors:
Treating it as a development project, not a business one
Focusing on platform choice over performance outcomes
Ignoring data and conversion optimisation
Leaving it until the last minute
The result? A new website… with the same old problems.
We don't see this as a migration.
We see it as an opportunity to accelerate measurable impact.
That means:
Starting with the commercial objective, not the CMS
Bringing together CRO, SEO, data, and development from day one
Designing platforms that are built to test, learn, and improve continuously
Because we're not here to just build websites.
We're here to create intelligent digital experiences, platforms that don't just look brilliant, but perform brilliantly too.
