Your network contains an Active Directory forest named adatum.com. All domain controllers run
Windows Server 2008 R2. The functional level of the domain and the forest is Windows Server 2008.
You deploy a new Active Directory forest named contoso.com. All domain controllers run Windows
Server 2012 R2. The functional level of the domain and the forest is Windows Server 2012 R2.
You establish a two-way, forest trust between the forests. Both networks contain member servers that
run either Windows Server 2012 R2, Windows Server 2012, Windows Server 2008 R2 or Windows Server
2008.
You plan to use the Active Directory Migration Tool 3.2 (ADMT 3.2) to migrate user accounts from
adatum.com to contoso.com. SID history will be used in contoso.com and passwords will be migrated by
using a Password Export Server (PES).
You need to recommend which changes must be implemented to support the planned migration.
Which two changes should you recommend? Each correct answer presents part of the solution.
A.
In the contoso.com forest, deploy a domain controller that runs Windows Server 2008 R2.
B.
In the adatum.com forest, upgrade the functional level of the forest and the domain.
C.
In the contoso.com forest, downgrade the functional level of the forest and the domain.
D.
In the adatum.com forest, deploy a domain controller that runs Windows Server 2012 R2.
Cause
ADMT 3.2 and PES 3.1 are not supported for installation on Windows Server 2012. The installers intentionally block unsupported operating systems.
Resolution
When you migrate to a Windows Server 2012 domain, install ADMT 3.2 on a Windows Server 2008 R2 server that can operate as the migration computer. You have to have a Windows Server 2008 R2 domain controller in the target environment.
Note If you already specified a Windows Server 2012 domain functional level, and you want the ADMT server to be a domain controller, you can lower the forest and domain functional level by using Windows PowerShell commands. For example, you can use commands that resemble the following:
Set-AdForestMode -identity contoso.com -forestmode Windows2008R2Forest
Set-AdDomainMode -identity contoso.com -domainmode Windows2008R2Domain
Windows Server 2012 implements only one feature, Dynamic Access Control, that has a Windows Server 2012 domain functional level requirement when the Windows Server 2012 domain is configured always to provide claims from all domain controllers. If you do not use this feature, you can lower the functional levels to support previous operating system domain controllers for ADMT migrations. When the migration is complete, you can raise the domain and forest functional levels back to Windows Server 2012.
ADMT v3.2 was re-released in 2013. All operating system checks were removed, previous versions of ADMT were deprecated.
