Hello my name is Paulo Viralhadas and I'm a Premier Field Engineer at Microsoft.
On one of my previous posts I wrote about vDC cloning which is my preferred feature in Windows Server 2012 "http://blogs.technet.com/b/reference_point/archive/2012/12/11/so-you-wanted-to-deploy-domain-controllers-faster-now-you-can.aspx".
VDC cloning gives you the ability to scale up your production forest and to recover from disasters faster, or simply to build a lab in a blink of the eye. In this post you may watch a number of videos that show how to clone a vDC.
Note: I tried to keep the videos as simple as possible for quick reference.
HOW TO CLONE A vDC
The Requirements are:Hypervisor must have support for VMGID (VM-Generation ID).ADDS schema version 56Windows Server 2003 Forest Functional Level.Source DC must be running Windows Server 2012.PDCe must be running on a Windows Server 2012 DC.PDCe and RID master online and available.
The video contents are:
Video 1 - Pre-requisit check.
Step 1 - Verify that the source VDC is running on a supported hypervisor.Step 2 - Verify Schema version.Step 3 - Verify Forest Functional Level.Step 4 - Check if the VDC source Operating System. Step 5 - Verify that the PDCe FSMO role is running on a Windows Server 2012 DCStep 6 - Ensure that PDC and RID master are available during cloning process.
Video 2 - Getting the Clone ready.
Step 7 - Create DCCloneConfig.xml file.Step 8 - Add the source VDC to the "Cloneable Domain Controllers" security group.Step 9 - Shutdown the source VDC.
Video 3 - Cloning...
Step 10 - Export the source VM (Virtual Machine).Step 11 - Import the VM with the option "Copy the virtual machine (create a new unique ID)".Step 12 - Start the new VM.
Step 1 - Verify that the source VDC is running on a supported hypervisor.
On the source vDC:open [Device Manager]expand [System Devices]open properties of [Microsoft Hyper-V Generation Counter]select the "Driver" tabclick "Driver details"verify that the driver is "vmgencounter.sys"This is the driver that makes vDC cloning and snapshot restore possible in Windows Server 2012.
Step 2 - Verify Schema version.
On any DC in the forest:run [regedit]browse to HKLM\System\CCS\Services\NTDS\Parametersverify that "Schema Version" REG_DWORD value is 56.This is the Windows Server 2012 version of the schema.
Step 3 - Verify Forest Functional Level.
On any DC in the forest:open [Powershell]run [Get-ADForest]verify that "ForestMode" value is "Windows2003Forest" or higher.
Step 4 - Check the vDC source Operating System.
On the source vDC:run [winver]verify that source vDC is a Windows Server 2012.
Step 5 - Verify that the PDCe FSMO role is running on a Windows Server 2012 DC
On any DC in the domain:open [cmd]run [netdom query fsmo]copy the PDC FQDNopen [Powershell]run [Get-ADDomainController -server <paste the PDC FQDN here>verify that OperatingSystemVersion value is 6.2 (9200) or higher
Step 6 - Ensure that PDC and RID master are available during cloning process.
Step 7 - Create DCCloneConfig.xml file.
open [Powershell]run [New-ADDCCloneconfigFile](this will create an empty configuration file, you might want to have a look on the table below before you add configuration information to this file)
Note: If you get a failure for applications not cloneable you have 2 options add them to the excluded application list or uninstall them from the DC
To see the list of unsupported applications run:
and to generate the XML file (thus adding the application(s) to the excluded list run:
Step 8 - Add the source VDC to the "Cloneable Domain Controllers" security group.
open [ADAC]browse your domain to the "Users" containerdouble-click "Cloneable Domain Controllers" security groupSelect "Members" tab and click "Add" button to add the source domain controller account
Step 9 - Shutdown the source VDC.
Step 10 - Export the source VM (Virtual Machine).
open [Hyper-V Manager]Right-click the source vDC VMSelect ExportSpecify where you want to save the files
Step 11 - Import the VM with the option "Copy the virtual machine (create a new unique ID)".
open [Hyper-V Manager]click on "Import Virtual Machine"Locate FolderSelect Virtual MachineChoose import type: "Copy the virtual machine (create a new unique ID)"
Step 12 - Start the new VM.
(Refer to the diagram below in order to understand the cloning/snapshot restore decision process)
The Cloning/Snapshot safeguards are:
