When running bin/config migrate, I got:
Migrating file-based config to more modern config... Skipping config of source type PhabricatorConfigDatabaseSource... Skipping config of source type PhabricatorConfigLocalSource... Migrating file source... Migrated option "phabricator.base-uri" from file to local config. Migrated option "mysql.host" from file to local config. Migrated option "mysql.user" from file to local config. PHP Fatal error: Call to undefined method PhabricatorContentSource::newFromConsole() in /opt/phabricator/phabricator/src/applications/config/management/PhabricatorConfigManagementMigrateWorkflow.php on line 61
This should probably not happen.
