Breaking: #82148 - Download SQL dump dropped in EM

See forge#82148


The "Download SQL Dump" feature in extension manager list view has been dropped, it is no longer possible to download the dump file this button created.


The button in the extension manager is gone along with various classes and methods that took care of the functionality:

  • Dropped class TYPO3\CMS\Extensionmanager\Utility\DatabaseUtility

  • Dropped class TYPO3\CMS\Extensionmanager\ViewHelpers\DownloadExtensionDataViewHelper

  • Dropped class TYPO3\CMS\Install\Service\SqlExpectedSchemaService

  • Dropped class TYPO3\CMS\Install\Service\SqlSchemaMigrationService

  • Dropped method TYPO3\CMS\Extensionmanager\Utility\FileHandlingUtility->sendSqlDumpFileToBrowserAndDelete()


The core provides the "Import / Export" extension to manage database data, furthermore the "List" module has an CSV export feature.

For true database backups we recommend the CLI tools of the database engine or dedicated GUI applications for this task.
