Windows2008R2Forest | Windows2012Forest | Windows2012R2Forest} [-AuthType {Negotiate | Basic}] [-Credential <PSCredential>] [-PassThru] [-Server <String>] [-Confirm]
[-WhatIf] [<CommonParameters>]
The Set-ADForestMode cmdlet sets the Forest mode for an Active Directory forest. You specify the forest mode by setting the ForestMode parameter.
The Identity parameter specifies the Active Directory forest to modify. You can identify a forest by its fully qualified domain name (FQDN), GUID, DNS host name, or NetBIOS
name. You can also specify the forest by passing a forest object through the pipeline. For example, you can use the Get-ADForest cmdlet to retrieve a forest object and then
pass the object through the pipeline to the Set-ADForestMode cmdlet.
Set-ADForestMode will prompt for confirmation by default.
