# Deprecation: #47712 - Deprecate old Locking API {#deprecation-47712}

See [forge#47712](https://forge.typo3.org/issues/47712)

## Description {#description}

The old class `TYPO3CMSCoreLockingLocker` has been marked as deprecated.

The configuration option `[SYS][lockingMode]` is now marked as deprecated and only affects the old Locker class, which is
unused in the Core now.

Moreover two unused methods of `TYPO3CMSFrontendControllerTypoScriptFrontendController` have been marked as deprecated:

-   acquirePageGenerationLock()
-   releasePageGenerationLock()

## Impact {#impact}

Using the old class will trigger deprecation log messages.

## Migration {#migration}

Use the new Locking Service API instead.
