Move bulk computer objects listed in TXT file to specific OU in Active Directory

List down the servers you want to move in a file named "server.txt".

Then find the correct OU where you want to move all computer objects.

Note: We assume we need to move the computer accounts in Servers OU under the nilabh.com domain.

Run the following script to move all computer objects listed in the notepad file to the required OU.

$Servers = Get-Content "C:\servers.txt"
$TargetOU = "OU=Servers,DC=nilabh,DC=com"

ForEach( $Computer in $Servers ) {
Get-ADComputer $Computer | Move-ADObject -TargetPath $TargetOU
}
