Windows 7/10 group policy template

Hi,

I have 300 Windows 7 pc's and plan on upgrading them to Windows 10 Enterprise. Our DC's are Windows Server 2016. I need to apply the Windows 10 group policy admin template.

1. what is the latest template for Windows 10 Enterprise?
2. how do I apply it? Do I copy it to \\dc\SYSVOL\xxx.local\Policies\PolicyDefinitions? Do I just copy the contents over? Will it break any existing Windows 7 GPOS?

Thanks.
