You have a single-domain Active Directory Domain Services (AD DS) forest. All servers run Windows Server 2008 R2. All client computers run Windows Vista. A custom local security group exists on all client computers. You are upgrading from Windows Vista to Windows 7. You will use User State Migration Tool (USMT) 4.0 to migrate user data and settings.
