Legacy Upgrade

Minor Upgrades - Using The Core Updater

The "Install Tool" in the section "Important Actions" provides a function to update the TYPO3 Core.

In the section "Important Actions" scroll down to "Core update" and click the "Check for core updates" button. If the requirements are met, TYPO3 will automatically install the new source code.


For the Core Updater to work, the following setup is required:

  • It only works in Unix-like systems (including macOS).

  • typo3_src must be a symlink.

  • This symlink needs to be writable (and deletable) by the web-server user.

  • The document root needs to be writable.

  • One path above document root (../) needs to be writable (creation of new directories must be allowed).

  • The tar command must be available (for extracting the Source package).

What's the Next Step?

In case you performed a minor update, e.g. from TYPO3 9.5.0 to 9.5.1, database updates are usually not necessary, though you still have to remove the temporary cache files. After that your update is finished.


Make sure to read the release notes of even the minor versions carefully. While great care is taken to keep the minor updates as easy as possible, (especially when releasing security updates) more steps might be necessary.

In case of a major update, e.g. from TYPO3 8.7 to 9.5, go ahead with the next step!
