Restructured company

I currently have an app listed in the App Store under my company's name. Recently, we restructured our company and adopted a new name that better reflects our product. My question is: Can I update our company name and DUN (Data Universal Numbering) number in the App Store, or do I need to create a new account for our restructured company? Alternatively, should I submit the updated version of the app under the original company name and DUN number?
