Before starting the upgrade check your system for compatibility with a newer
TYPO3 version.

  Upgrade Wizards of the the current TYPO3 major version.

* Check for deprecations: Enable the deprecation log and let it log all
  deprecations for a while.

* Alternatively (or additionally) run the
  :ref:`extension scanner <t3coreapi:extension-scanner>` and
  :ref:`handle deprecations <handling-deprecations>` (below).

* Check installed extensions for versions compatible to the target TYPO3
  version

* Try the upgrade on a development system first or create a parallel instance


Check that all system requirements for upgrading are met:
