Active directory Migration from windows server 2003 to windows server 2012 with DHCP Role

We are Migrating Current Active directory 2003 to windows server 2012 with DHCP role.

We have windows server 2012 core on which hyper v is configured and in hyper v we have installed windows server 2012 for the migration of active directory from windows server 2003.

We have successfully migrated AD and DNS role and transferred all FSMO roles to new Windows server 2012 server.

But we have issue with DHCP.

We have Export DHCP  settings from windows server 2003 and than import in windows server 2012 server. we have followed below steps for this.

on 2003 Domain controller
open cmd as a Administrator and run netsh dhcp server export c:\dhcp.txt all
copy dhcp.txt file to new domain controller windows server 2012
on 2012 Domain controller
open cmd as a Administrator and run netsh dhcp server import c:\dhcp.txt all

Authorized dhcp server on windows server 2012 and disable DHCP role in 2003 domain controller and trying to get lease from 2012 domain controller.

Lease can not be getting form new 2012 domain controller. The IP is getting on a client machine is 169.252.x.x

 we have restarted service twice and checked event log and got below details

"The DHCP\BINL service on the local machine belonging to the windows administrative domain contoso.com has determine that authorized to start. it is servicing clients now."

Is there any configuration is missing in a hyper v or in dhcp ??

Kindly suggest....

Quick response highly appreciable....
