Checklist to validate that AD Site, Subnets, and Costs have been applied properly and working

Hello,
WE are upgrading all the environment from 2003 to 2012 DC. WE are building all new 2012 r2 DCs and migrating the DNS and DHCP. What would be the steps to validate that AD Site, Subnets, and Costs have been applied properly and working. Also, we need to validate that users are being authenticated by the Domain Controller within their geographic site  and receive GPO from their geographic zone and not from DC somewhere else. Could you please let me know how to do it and all the commands/steps that I need to run. THank you very much.

All the sites and subnets from the existing environment will still apply in the new environment.  You shouldn't have to do anything with that other than at least confirm there are connection objects created between the new DC's and the old DC's in your various sites in sites and services.  Make sure at least one of the new DC's is configured as a global catalog server as well (if not all of them).
