### Websites Upgrade
Should you Upgrade TYPO3 Website or Relaunch?
---------------------------------------------
If you want to improve your TYPO3 website, you are faced with 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 look at the differences so you can make an informed decision.
### Upgrade TYPO3 Website
A TYPO3 upgrade means that you update your content management system (CMS) from an old version to a new version. This usually involves several major versions, for example from version 9 to version 11.
- Upgrade from an older TYPO3 version (e.g., from v8 or v9 to v10 or v11).
- The design and structure of the website remain largely unchanged.
- Third-party extensions and tools are updated for compatibility.
- The focus is on backend improvements, performance, and security.
- Less time and money required compared to a complete relaunch.
#### Upgrade Your TYPO3 Website
Still using an older TYPO3 version? Perform an upgrade now – for better performance, increased security, legal compliance, and full compatibility with the latest extensions.

### Relaunch TYPO3 Website
A TYPO3 relaunch is much more than just a simple technical upgrade. It is a complete and thorough redesign of your entire business website. Sometimes this also includes new creative design and features.
- Updating your outdated company website from a very old TYPO3 version (e.g., v4, v6, or v7).
- Introducing a modern, user-friendly new design, refreshed branding, or a fully revised customer journey.
- Replacing outdated, insecure legacy extensions with reliable, secure, and modern alternatives.
- Use of innovative new frameworks or modern front-end technologies (e.g., headless, PWA, React, or Vue).
- Offers maximum flexibility to adapt to the company's growth and goals.
