Get Obsolete Computer Object And Move them, Using PowerShell

Using this script you will be able to get all the computer Object in your AD, read the LastloginTimeStamp


import-module activedirectory #Add Active Directory Module to powershell
cls #Clear the console
$now=Get-Date #get the current Date
$now=$now.AddMonths(-7) #7 Month Ago
$Servers=Get-ADComputer -Properties lastLogonTimestamp -Filter {lastLogonTimestamp -lt $now}| select name,@{N='lastLogonTimestamp'; E={[DateTime]::FromFileTime($_.lastLogonTimestamp)}}
#filter the returned result to store only computer objects with LastloginTimeStamp before 7 month, I will read the lastLogonTimeStamp for each computer along with the Computer Name (Note: the -lt mean Less Than) 
foreach ($SingleServer in $Servers){ # to read each object in the $Server Variable 
$ODN = Get-ADComputer -Identity $SingleServer.name -Properties distinguishedName | select distinguishedName #We will need to get each computer DN and pass it to Move-ADObject, as Move-ADObject can not read computer name, it must read DN 
Move-ADObject $ODN.distinguishedName -TargetPath "OU=Disabled Objects,DC=Domain,DC=local"
}

you may get an error when running this script telling Cannot validate argument on parameter 'Identity'. The argument is null. This is because the returned result from $ODN=Get-ADComputer is Null as there is no computer which have LastloginTimeStamp value match the filter.
