We have two DC both are running 2008 R2
DC1 - All FSMO roles, AD integrated DNS (VM)
DC2 - DC, AD integrated DNS (VM)
SRV1 - DHCP windows 2003 (VM)
I want to add 2012 R2 (Physical) as DC and want to move DHCP to 2012 R2 server.
Need to migrate FRS to DFSR.
Show question is should I migrate FRS to DFSR first before adding another DC running 2012 R2 or after adding it?
or add 2012 R2 first then move DHCP to 2012 R2 and then migrate FRS to DFSR?
Instructions to migrate FRS from another SW topic https://blogs.technet.microsoft.com/filecab/2014/06/25/streamlined-migration-of-frs-to-dfsr-sysvol/
Can you also provide me working instructions on migrating DHCP from 2003 to 2012?
Also, I need to add processor on existing DC servers which are VM any issues doing that specially on DC? I have tested on another 2008 server and did not cause any issues?
