ActiveDirectory add backup domain controller on other computer

Question

I have Active Directory and need to move to another ActiveDirectory(PDC) on the other computer and I want to do it this way:

• Add a Backup Domain Controller
• Synchronize the settings from Primary Domain Controller i.e import the settings
• Make BDC as PDC(i.e switch them vice versa)
• and "deactivate" new BDC(the old PDC)

It looks great but I need to know HOW can I implement it?

Environment:

OS - MS Windows Server 2008 R2(both PCs)

Answer 1

It's a lot simpler then that:

• Use DCPROMO to make a new Domain Controller.
• Move the Functional Roles from one to the other.
  • Schema Master (from the AD Schema MMC)
  • Domain Naming Master (from AD Sites and Trusts)
  • Relative ID Master (from ADU&C)
  • Primary Domain Controller Emulator (from ADU&C, only useful for NT services)
  • Infrastructure Master (from ADU&C)
• If needed turn on DNS services on the new DC.
  • Update any DHCP settings to advertise the new DNS server, or hand-update your statically assigned machines.
• Use DCPROMO to demote the old Domain Controller.

The concept of a "Backup Domain Controller" was deprecated when Windows 2000 released. By Server 2008 R2 there is no concept like it. All domain controllers, except for Read-Only Domain Controllers, can do everything the NT PDC used to do. People get confused by that "PDC Emulator" role, all that is is a role to name one server as the PDC for very old software that expects there to be one and only one of those in a domain.
