IMPORTANT: Only the Administrator of your Innovation Cloud account can remove roles and choose a new Administrator. Each user can be set with only one role.
To set the Administrator role, please go to the System settings > User management tab.
Select the user you want to assign an Administrator role to and click on the pencil located on the right side of the each userbox. In the user information page, select an Administrator role and Save changes.
Note: Users can be set with only one role, so replacing that role with a new one, gives the user different access.
