In the episode regarding migrating roles to new 2012 machines you migrated the DHCP role. I found information regarding supported roles to be transferred and did not see DHCP. Would you be able to direct me to the documentation regarding migrating that DHCP role? Thanks.
2012 server migration tools
The import/export process is documented in this TechNet posting:
That article covers moving DHCP from Windows Server 2008 to Windows Server 2012. I have not done a migration from Windows Server 2003 straight to 2012, but I would be surprised if it did not work. Even without the power shell commands you will likely be able to move the DHCP database files over as they have barely changed since Windows Server 2003.
Hope that helps,
