# Deprecation: #107931 - Lowlevel DatabaseIntegrityCheck class {#deprecation-107931-1775647667}

See [forge#107931](https://forge.typo3.org/issues/107931)

## Description {#description}

The class `\TYPO3\CMS\Lowlevel\Integrity\DatabaseIntegrityCheck` has been
deprecated and will be removed in TYPO3 v15.0.

The class is no longer used internally by TYPO3 and should not be relied upon
by extensions.

## Impact {#impact}

Using `DatabaseIntegrityCheck` will trigger
a PHP `E_USER_DEPRECATED` error. The class will be removed in TYPO3 v15.0.

## Affected installations {#affected-installations}

TYPO3 installations with extensions that use
`DatabaseIntegrityCheck` directly.

## Migration {#migration}

Extensions that rely on this class should implement the necessary functionality
themselves.
