I am planning to migrate our existing domain controllers from one network to the other. My plan is to build new domain controllers in other network and allow Domain controller to replicate. There is no firewall between two networks. I had a looked at this link: http://blogs.technet.com/b/canitpro/archive/2014/04/02/step-by-step-active-directory-migration-from-windows-server-2003-to-windows-server-2012.aspx This link gives instructions to migrate from 2003 to 2012. My question is does the same instructions apply to 2012 to 2012 migration?
Is the step "Changing Schema master" needs to be performed on all primary and backup domain controllers?
