Copying users from one AD group to another

How to copy the group membership of one AD group to another

$FromG = "MySourceGroup"
$ToG = "MyDestinationGroup"

Add-ADGroupMember $ToG -member ((Get-ADGroupMember $FromG).DistinguishedName)

Well, that's all fine but the script will choke if the source group has any of the following characteristics:

• More than 1,500 objects inside
• Has any foreign security principles inside (members of trusted domains)
• Has any nested groups inside

Here is a more robust version:

$FromG = "MySourceGroup"

$ToG = "MyDestinationGroup"

Get-ADGroup $FromG -Properties Member |Select-Object -ExpandProperty Member|ForEach-Object `

{

Add-ADGroupMember $ToG -Member $_

}

Cheers!
