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?

Yes, if you are simply adding new DCs all you should need to do is add the DCs, replicate, move any FSMO roles, then demote the old DCs. However you can skip the regsvr part if you transfer the role on the machine its already registered on.
