Dear Friends,

I am really confused about DHCP migration.

Now we have two old DC servers on 2012 R2 servers, both is running DHCP, they are replicated to each other. Is there a Master DHCP server?

Now I would like set up new server 2019 and transfer FSMO role to the new box. SHould I set up a DHCP replica on server 2019? And remove DHCP one by one on old Server 2012 R2? or I should back up DHCP, and set up a new DHCP service on the server 2019 and import to DHCP?

Thanks a lot,
ML

    Yes, sounds good, you could also export beforehand (for backup) and before beginning the work.
