Backing up F5 config's

Okay so we have several Big IP F5's of both 4000 and 3600 series, they all live on different versions of O/S.

I have got the config from a 4000 running version 11.6 to backup, but the 4000 running 12.0.0 will not.

Below is the script we are using that works on version 11.6

<Configuration-Management Device="F5 Big IP" SystemOID=" 1.3.6.1.4.1.9">

  <Commands>

  <Command Name="RESET" Value=""/>

  <Command Name="Reboot" Value=""/>

  <Command Name="EnterConfigMode" Value=""/>

  <Command Name="ExitConfigMode" Value=""/>

  <Command Name="Startup" Value="ucs" IsBinary="true"/>

  <Command Name="Running" Value="config file"/>

  <Command Name="DownloadConfig" Value="show running-config"/>

  <Command Name="UploadConfig" Value=""/>

  <Command Name="DownloadConfigIndirect" Value=""/>

  <Command Name="UploadConfigIndirect" Value=""/>

  <Command Name="DownloadConfigIndirectSCP" Value=" save /sys ${ConfigType} /var/local/NCM.ucs${CRLF}${TransferProtocol} /var/local/NCM.ucs ${SCPServerUserName}@${SCPStorageAddress}:${StorageFilename}${CRLF}yes${CRLF}${SCPServerPassword}"/>

  <Command Name="UploadConfigIndirectSCP" Value="${TransferProtocol} ${SCPServerUserName}@${SCPStorageAddress}:${StorageFilename} /var/local/NCM.ucs${CRLF}${SCPServerPassword}${CRLF}tmsh load /sys ${ConfigType} /var/local/NCM.ucs"/>

  <Command Name="EraseConfig" Value=""/>

  <Command Name="SaveConfig" Value=""/>

  <Command Name="Version" Value="show /sys version"/>

  <Command Name="Disconnect" Value=""/>

  </Commands>

</Configuration-Management>

Can anybody help at all ?

Regards

Scott.
