# Deprecation: #89554 - Deprecate \\TYPO3\\CMS\\Extbase\\Mvc\\Controller\\AbstractController {#deprecation-89554}

See [forge#89554](https://forge.typo3.org/issues/89554)

## Description {#description}

The class `\TYPO3\CMS\Extbase\Mvc\Controller\AbstractController` has been marked as deprecated.

The `AbstractController` is an internal class which never really had any functionality besides
providing some basic methods for the `\TYPO3\CMS\Extbase\Mvc\Controller\ActionController`. Therefore
and in order to streamline the codebase of extbase, the `AbstractController` will be removed
with TYPO3 11.0.

## Impact {#impact}

As all functionality of the `AbstractController` has been moved to the `ActionController` there is no impact
for extbase extensions that used and extended the `ActionController`.

## Affected Installations {#affected-installations}

Installations that extended the `AbstractController` directly.

## Migration {#migration}

Extend the `ActionController`.
