I had the same problem but in changing a netflix account, not from an upgrade.
i went on to account settings on your tv and went to log in, on this page it showed my email and password. The box saying 'remember my password was checked' but there was another box saying 'sign me in automatically' i checked this and hey presto netflix opened with my new account!
