Upgrading extensions

How you upgrade extensions depends on your role and project setup:

  • If you use third-party extensions, update them via Composer or the Extension Manager.
  • If you maintain your own custom extension or site package, refer to the dedicated guide on updating your codebase.

Managing extensions via Extension Manager

For projects not using Composer, extensions can be installed and updated using the TYPO3 backend's Extension Manager.

Maintaining your own extension

If you maintain a custom extension or site package, see this guide for tips on versioning, upgrading for new TYPO3 releases, and ensuring compatibility.
