A question regarding DHCP failover in Windows 2016

november24

I read the following two paragraphs on the same page:

"Scope settings are replicated when you first configure DHCP failover and can be replicated again later if configuration changes are made.

If parameters of a failover-enabled scope are modified, these settings must be manually replicated to the partner DHCP server. Note: Automatic replication of scope settings is available if you use IP address management (IPAM) in Windows Server 2012 R2 to modify failover-enabled scope settings."

Pasted from <https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2012-R2-and-2012/dn338983%28v%3dws.11%29>

 

so, I am confused now. which one is correct?
