Should you Upgrade TYPO3 Website or Relaunch?

When it comes to improving your TYPO3 website, you are likely facing an important decision: Should you upgrade or consider a complete relaunch? Both approaches have their advantages depending on the current state of your website, your goals, and future requirements. Let's consider the differences to help you make an informed decision.

Upgrade TYPO3 Website

A TYPO3 upgrade refers to updating your CMS from an older version to a newer one – typically across major versions (e.g., from version 9 to version 11).

  • Upgrading from an older TYPO3 version (e.g., v8 or v9 to v10 or v11).
  • The design and structure of the website remain mostly unchanged.
  • Extensions and third-party tools are updated for compatibility.
  • The focus is on backend improvements, performance, and security.
  • Lower time and cost investment compared to a complete relaunch.

Relaunch TYPO3 Website

A TYPO3 relaunch is more than just an upgrade – it’s a complete re-development of your website, sometimes includes a new design.

  • Updating your website from a very old TYPO3 version (e.g., v4 or v6).
  • Introducing a new design, re-branding, or a revised user journey.
  • Replacing outdated extensions with the latest alternatives.
  • Using new frameworks or modern frontend technologies (e.g., Headless, PWA).
  • Offers maximum flexibility to align with business growth and goals.

What does a TYPO3 upgrade cost?

The cost of a TYPO3 upgrade varies depending on the scope of the project. As a rule, the prices range between 2.000 € and 10.000 € depending on factors such as the current TYPO3 version, the number of extensions and whether a redesign is desired.

At NITSAN, we offer transparent and fair pricing based on a detailed analysis of your website. Our goal is to provide you with a customized solution that both fits your budget and brings your website up to date.
