Wrong credentials entered during Client update

Hi,

We have a production site where ODS transfer have stopped working after an upgrade
from 6.0.4.12 to 6.0.4.18.

I am suspecting that the wrong database credentials have been given during client upgrade and
I want to change them to make sure they are correct. Since this is now encrypted information
I have no file that I can update.

How can I change the created database credentials after an update to the client is done?

Best regards,

Johan
