CRM Online with Connector (NAV), new flow GUI?

Hi,

When setting up Connector for CRM Online and NAV the installation document states that you need to use the "classic view" in CRM.

Installation video that refer to the subject in mind:

I know I can change this "globally" in CRM by following the guide below:

However, I need to make sure that this is the correct approach, is there another way to make classic view global for CRM?

Thanks in advance.
