See forge#85727

Description

The PHP class \TYPO3\CMS\Core\Integrity\DatabaseIntegrityCheck has been moved from the system extension core to lowlevel. The PHP class has been renamed to \TYPO3\CMS\Lowlevel\Integrity\DatabaseIntegrityCheck .

Impact

Calling the old class name will trigger a PHP E_USER_DEPRECATED error.

Affected Installations

Any TYPO3 installation where this PHP class is in use within a TYPO3 extension.

Migration

Ensure that the system extension lowlevel is installed, and the caller code uses the new class name.

For TYPO3 v9, the old class is kept in place and will be removed in TYPO3 v10.
