Description
The Copy-GPO
cmdlet creates a destination Group Policy Object (GPO) and copies the settings from
the source GPO to the new GPO. The cmdlet can be used to copy a GPO from one domain to another
domain within the same forest. You can specify a migration table to map security principals and
paths when copying across domains. You can also specify whether to copy the access control list
(ACL) from the source GPO to the destination GPO.
This cmdlet does not copy the source GPO if a GPO with the specified target display name already exists in the destination domain. In this case, an error occurs and the GPO is not copied.
Examples
Example 1: Copy a GPO
Copy-GPO -SourceName "TestGpo1" -TargetName "TestGpo2"
DisplayName : TestGpo2
DomainName : contoso.com
Owner : CONTOSO\Domain
Admins Id : 37eeb072-cc31-42bb-8c3a-446c2b6ddd3f
GpoStatus : AllSettingsEnabled
Description :
CreationTime : 2/25/2009 9:12:05 PM
ModificationTime : 2/25/2009 9:12:05 PM
UserVersion : AD Version: 1, SysVol Version: 1
ComputerVersion : AD Version: 1, SysVol Version: 1
WmiFilter :
This command copies the TestGpo1
GPO to a GPO named TestGpo2
.
The GPOs exist in the domain of the user that is running the session.
Example 2: Copy a GPO from a domain to another domain
$params = @{
SourceName = 'TestGpo1"'
SourceDomain = 'test.contoso.com'
TargetName = 'TestGpo1'
TargetDomain = 'sales.contoso.com'
}
Copy-GPO @params
This command copies the TestGpo1
GPO from the test.contoso.com
domain to a GPO named TestGpo1
in the sales.contoso.com
domain.
A trust relationship must exist between the source domain and the destination domain. In addition, if the source domain or the destination domain (or both) is different than the domain of the user that is running the session.a trust must exist between that domain and the domain of the user.
Example 3: Copy all GPOs from a domain to another domain
Get-GPO -All -Domain "sales1.contoso.com" | ForEach-Object {
$params = @{
'TargetName' = $_.DisplayName
'TargetDomain' = "sales2.contoso.com"
'CopyACL' = $true
'MigrationTable' = 'c:\tables\MigrationTable.migtable'
}
$_ | Copy-GPO @params }
This command copies all the GPOs in the sales1.contoso.com
domain to the sales2.contoso.com
domain.
All the GPOs in the source domain are retrieved by using the Get-GPO
cmdlet using the All
parameter. The output of Get-GPO
is piped into the ForEach-Object
command. When each GPO is
evaluated, it is piped into Copy-GPO
and its display name is specified for the TargetName
parameter -TargetName ($_.DisplayName)
. The CopyACL parameter is specified to copy the ACLs
for each GPO to the destination domain. The MigrationTable parameter specifies a migration table
to use to migrate Security principals and UNC paths to the destination domain. Both the CopyACL
and the MigrationTable parameters are optional.
If a GPO with the same display name as a source GPO already exists in the destination domain, an
error occurs when this command attempts to copy the source GPO. Because this command copies all GPOs
in the source domain, errors occur for default GPOs; for instance, the Default Domain Policy GPO and
the Default Domain Controllers Policy GPO. These GPOs are not copied. You can suppress these error
messages by supplying the ErrorAction parameter with a value of SilentlyContinue to
Copy-GPO
. For more information about the ErrorAction parameter, see
about_CommonParameters.
The destination GPOs that were successfully copied are returned by this command. By default, they
are printed to the display, but you can add commands to the end of the pipeline to further configure
these GPOs. For example you can add a Set-GPLink
cmdlet to the end of the pipeline to link all the
destination GPOs to a site, domain, or organizational unit.
A trust relationship must exist between the source domain and the destination domain. In addition, if the source domain or the destination domain (or both) is different than the domain of the user that is running the session a trust must exist between that domain and the domain of the user or the computer.

-MigrationTable
Specifies the location of the migration table to use for the command. You must specify the full path
to the file; for instance, \\Server1\MigrationTables\TestToSalesTable.migtable
. If you supply a
migration table, security principals and Universal Naming Convention (UNC) paths are mapped to the

Default value: | None |
Required: | False |
Accept pipeline input: | False |
Accept wildcard characters: | False |
-SourceDomain
Specifies the domain of the source GPO. You must specify the fully qualified domain name (FQDN) of the domain.
If you do not specify the SourceDomain parameter, the domain of the user that is running the current session is used. If the cmdlet is being run from a computer startup or shutdown script, the domain of the computer is used. For more information, see the Notes section in the full Help.
If you specify a domain that is different from the domain of the user that is running the current session (or, for a startup or shutdown script, the computer), a trust must exist between that domain and the domain of the user or the computer.
You can also refer to the SourceDomain parameter by its built-in alias, DomainName. For more information, see about_Aliases.

Inputs
Microsoft.GroupPolicy.Gpo
The cmdlet takes a GPO as input. GPO objects that are piped into the cmdlet are used as the source GPO. Collections that contain GPOs from different domains are not supported.
Outputs
Microsoft.GroupPolicy.Gpo
This cmdlet outputs a copy of the specified GPO.
Notes
You can use the
Copy-GPO
cmdlet to copy a GPO within a domain or from one domain to another within the same forest.You can use the SourceDomain and TargetDomain parameters to explicitly specify the source domain or the target domain for this cmdlet.
If you do not explicitly specify the domain, the cmdlet uses a default domain. The default domain is the domain that is used to access network resources by the security context under which the current session is running. This domain is typically the domain of the user that is running the session. For example, the domain of the user who started the session by opening Windows PowerShell from the Program Files menu, or the domain of a user that is specified in a runas command. However, computer startup and shutdown scripts run under the context of the LocalSystem account. The LocalSystem account is a built-in local account, and it accesses network resources under the context of the computer account. Therefore, when this cmdlet is run from a startup or shutdown script, the default domain is the domain to which the computer is joined.
