 {
    #Get the Source List
 $SourceList =(Get-SPWeb $SourceWebURL).Lists[$ListName]

    #Export the List from Source web
    Export-SPweb $SourceWebURL -ItemUrl $SourceList.DefaultViewUrl -IncludeUserSecurity -IncludeVersions All -path ($BackupPath + $ListName + ".cmp") -nologfile

   #Import the List to Target Web
