How Much Does an Umbraco 13 to 17 Upgrade Cost?
Umbraco
Most agencies won't give you a straight answer. They'll say, "it depends" and leave you to chase a quote through a sales call. We'd rather just tell you.
The Straight Answer
- €17,999 for a full Umbraco 13 to 17 upgrade
- Covers a multilingual site, a decoupled front end, and live integrations like payments and CRM
- Delivered in about 10 weeks
What That Covers
- Moving the site through every version between 13 and 17
- Migrating your content and structure
- Reconnecting every integration
- Full testing before anything goes live
Why Umbraco 17
Runs on .NET 10, Microsoft's newest long-term-supported framework, the most stable release Umbraco has shipped in years, and a genuine long-term-support version rather than a stopgap you'll be upgrading off again soon.
Key Features
- Editing backend can scale across multiple servers as your team and traffic grow
- Scheduled publishing stays accurate across time zones, so nothing goes live at the wrong time
- Built-in accessibility improvements make the editing experience easier for more people
Why This Can't Wait
- Umbraco 13 reaches end of life on December 14, 2026
- No more security updates after that date
- Agencies get booked out fast as the deadline nears
- Start now, and the upgrade happens on your schedule, not a last-minute scramble
Don't Wait for the Deadline to Decide for You
- Every day on Umbraco 13 is one day closer to running unsupported software
- Your exact number takes one message to find out, not weeks of back and forth
- No generic quote, no guesswork, just what your site actually needs, priced straight

Frequently Asked Questions
It depends. Personalization, customization, and third-party packages can add to the scope. €17,999 covers a standard project, anything beyond that gets sized during your free consultation, before you commit to anything.
About 10 weeks for a typical project, start to finish. Simpler sites can move faster.
No. The upgrade is built and tested on a separate environment first. Your live site stays untouched until everything's ready to go.
More content means more to migrate and test, which can affect timeline and cost but not the process itself. Fill out the form above and we'll give you a specific number after a quick look.
Yes, payment gateways, CRM systems, email tools, and multilingual content are all standard parts of an upgrade scope.
That's not a problem. Headless setups where a separate front end pulls content from Umbraco upgrade the same way. We upgrade the CMS side and make sure the connection to your front end keeps working exactly as it should.
Yes. If you're already planning an upgrade, it's a good moment to move to headless too, since Umbraco 17 supports it natively.
Your site keeps running, but Umbraco 13 stops receiving security updates after December 14, 2026, so any vulnerability found after that date goes unpatched.
If your timeline runs past December 14, 2026, we arrange Umbraco's Extended Support in advance so there's no gap in coverage, your site stays protected the entire time, even mid-upgrade.
As an official Umbraco partner, Arroact has a direct line to Umbraco itself, including access to Extended Support if your project runs past the EOL deadline. That's a safety net most non-partner agencies simply can't offer.
