[TYPO3-english] Upgrade from 4.4 to 6.0 Backend is blank

[jacopo migliorelli]

Hi everyone,
I have made an upgrade from 4.4. to 6.0 but it didnt work.
here what I did:
- copy typo3, t3lib, index.php, .htaccess
- Upgrade wizard
The install tool is visible but when I try to do the upgrade wizard he gives me this error
caller 	TYPO3\CMS\Core\Database\DatabaseConnection::exec_SELECTquery
ERROR 	Table 'designerdock_typo3_utf8_design.backend_layout' doesn't exist

php version is 5.3-7 

Do you have any Tipps?
Thanx in advance
Jacopo
