Downlaoding GUP Content Manually

Hi,

I'm running SEPM 12.1.4013.4013 and clients are on 12.1.3.

I have a situation whereby I would like to download GUP content manually. I realise this sounds odd but would just like to know if its possible.

I know a jdb file can manually update the SEPM but is the such a file with which to manually update a GUP?

Many Thanks
