Migrate a domain controller from Windows 2003 to Windows 2008
In this Will be doing a Migrating from a windows server 2003 sp2 standard to 2008 R2 64 bit Windows Server.
The Domian Name Sccmtest.com
Roles in the server : DNS,
1. 1st step open command prompt and run the following commands, make sure first to browse to the adprep directory inside the Windows 2008 DVD , in my case, the D drive is the DVD Drive letter, so to browse to the adprep directory (Eg: cd D:\sources\adprerp)
· adprep/ forestprep
· adprep/ domainprep
· adprep/ rodcprep (Optional, if you plan to add a Read Only Domain Controller Later)
Like in the above Image run the all 3 command.
2nd step create the Windows 2008 X64 Server (that will be the New DC)
3rd Add the new server to the domain And promote it as ADC ( when you’re doing the Dcprome install the DNS Role As well)
Moving the FSMO roles to the new Domain Controller.
Change the Operations Master
(Active Directory Domains and Trusts MMC rite click go to connect to domain controllers and select the new DC)
The click Operations Master and Change.
Change the Schema Master
Run the following command regsvr32 schmmgmt.dll.
Add the Schema Snap-in in your Management Console.
Change the RID Master, PDC Emulator and the Infrastructure Master.
Go to Active Directory Users and Computers
Click on change RID Master, PDC Emulator and the Infrastructure Master.
All the FSMO roles are transfered to the new Server 2008 Domain Controller. Now demote the Windows 2003 Domain Controller by running the DCPROMO command.
And Restart the Old Server
