People,

I've got two 2008 R2 AD Domain Controller that is running also as Global Catalog in one of my AD site.
It doesn't run any of the FSMO roles, but it is currently serving as AD integrated DNS server and also DHCP server for the subnet.

I have deployed 2x Win 2012 R2 VMs but now I'm confused myself. Should I:

#1 Migrate both DNS and DHCP (I will setup DHCP resiliency in the two new 2012R2) first, then DCPROMO after
#2 DCPROMO the two new 2012 R2 VMs as DC/GC and then migrate both DHCP & DNS server

Which one is better or the most recommended way ?
