Umbraco 17 Upgrade

Upgrade to Umbraco 17 with Confidence

Umbraco 13 support ends on 14 December 2026

Once Umbraco 13 reaches end of life, it will no longer receive standard security patches, updates or ongoing support.

Your website may continue to operate, but remaining on an unsupported CMS could increase security risks, create compatibility issues and make future development more difficult and expensive.

Clear Upgrade Path from Terabyte

Moving from Umbraco 13 to Umbraco 17 is more than a routine software update. Your custom functionality, integrations, packages and content structure may all need to be reviewed.

Terabyte can manage the full process, including:

  • Technical discovery and platform assessment

  • A clear upgrade recommendation and scope

  • CMS and front-end development

  • Package and integration updates

  • Content migration

  • Quality assurance and testing

  • Deployment and go-live support

You will receive a practical upgrade plan, clear commercial expectations and support from an experienced New Zealand-based digital team.

Now's the time to plan your upgrade.
