How to migrate DHCP configuration from two DHCP servers configured for failover hot-standby?

Are there any good articles, documentation, videos on how to migrate DHCP configuration?

Existing environment:

1) Two DHCP servers running Window Server 2016 Standard where each scope is configured with DHCP failover in stand-by mode.

2) Need to standup a third (new) DHCP server with the same scope configurations as the two current DHCP servers.

3) Need to decommission one of the original two DHCP servers that is already a member of the failover.

What is Microsoft best practices to accomplish this?

Do we need to break the failover relationship prior to starting this project?

Thank you

    Hello @Andrew Marshe ,

    There is no specific "best practice" as it is very straight forward:
    1- Set up an add the new member to the DHCP Failover pool
    2- Disconnect the Failover member to be decommissioned. Test assignment, routing, and leave at least a 2 week period for eventual issue detection.
    3- After the time that is confirmed to work successful, you can proceed to remove the relationship and decommission the server.

    Hope this helps with your question,
