I have two DCs that are on 2008 R2. I want to move AD and DHCP to two new DCs on Server 2012. I want the two new DCs to have Fail-over AD and DHCP servers. I figure i'll do this in two steps.
1. Move DHCP to the new servers
2. Move AD
I know that Server 2012 allows me to export DCHP server configuration and leases and then import the info into the server 2012 DHCP servers which looks pretty straight forward by using:
Export-DhcpServer –ComputerName win2k8r2-dhcp.corp.contoso.com -Leases -File C:\export\dhcpexp.xml -verbose
Import-DhcpServer –ComputerName DHCP1.corp.contoso.com -Leases –File C:\export\dhcpexp.xml -BackupPath C:\dhcp\backup\ -Verbose
My question is how will the network start using the new DHCP server rather than the old. I'm assuming that there is an "Activate" command or something?
