The Upgrade Wizard shows me this error by trying to procced the step " Migrate backend users’ selected UI languages to new format.":

Doctrine\DBAL\Exception\DriverException

An exception occurred while executing ‘UPDATE be_users SET lang = ? WHERE uid = ?’ with params [“default”, 1]: Data too long for column ‘lang’ at row 1

Data too long for column ‘lang’ at row 1

Any suggestions to this error message?

Solved this issue by running " Analyze Database Structure" first and let him change and create all necessary fields / tables.
