You Have A Forest That Includes Five Domains And Two Trees It Contain

You have a forest that includes five domains and two trees. It contains the following domains: Contoso.com with 3 Windows Server 2003 R2 domain controllers, Support.contoso.com with 3 Windows Server 2003 R2 domain controllers and 1 Windows Server 2008 R2 domain controller, Sales.contoso.com with 3 Windows Server 2008 domain controllers, Litware.com with 2 Windows Server 2003 domain controllers and 1 Windows 2000 Server domain controller, and Partner.litware.com with 2 Windows Server 2003 R2 domain controllers.

What are the steps you need to promote the forest to the Windows Server 2012 functional level? (minimum 150 words)

Paper For Above instruction

To upgrade a forest to the Windows Server 2012 functional level, several preparatory and procedural steps are required, especially considering the current environment includes older domain controllers such as Windows Server 2000 and Windows Server 2003 R2. The primary goal is to ensure all domain controllers are compatible with Windows Server 2012, which requires raising the functional level only after all domain controllers in the forest are upgraded or replaced with Windows Server 2012 or higher versions.

The first step involves auditing the existing environment to determine the presence of legacy domain controllers like Windows Server 2000 or Windows Server 2003 R2. Given that Windows Server 2000 Domain Controllers are no longer supported and incompatible with Windows Server 2012, these need to be migrated or decommissioned. In this case, the domain controllers running Windows Server 2000 and Windows Server 2003 R2 in the Litware.com domain, for example, must be replaced with Windows Server 2012 Domain Controllers to ensure compatibility across the forest.

Next, upgrade or add new Windows Server 2012 Domain Controllers to each domain within the forest, ensuring the new controllers hold the Flexible Single Master Operations (FSMO) roles that are crucial for domain and forest operations. After deploying Windows Server 2012 Domain Controllers in all domains, verify replication and synchronization across all domain controllers. This ensures consistency and readiness for the functional level upgrade.

Once all the domain controllers run Windows Server 2012 and replication is verified, the next step involves raising the domain functional level to Windows Server 2012 for each domain. This can be achieved via Active Directory Domains and Trusts or PowerShell commands, ensuring that any previous domain controller versions are decommissioned.

Finally, after all domains are upgraded to the Windows Server 2012 domain functional level, the forest itself can be raised to the Windows Server 2012 forest functional level. This step is typically performed through Active Directory Domains and Trusts, selecting the 'Raise Forest Functional Level' option, which enables new features in Active Directory and improves overall security and management.

In summary, the process involves decommissioning older domain controllers, deploying Windows Server 2012 Domain Controllers, verifying replication, upgrading each domain's functional level, and then raising the forest functional level. These steps ensure a smooth transition to the Windows Server 2012 environment, unlocking advanced features and enhanced security features native to this release, thereby future-proofing the network infrastructure.
