Hi,

You would have to do that inside the guest…the same way as you would do it on real hardware…mount both disks, move the relevant data
not trivial and not automated

so you want to have a preinstalled OS…so how did you want to use it?
I probably don't understand what are you trying to achieve.
Anything else than having a Template with OS and you deploy VMs from that….you need to change disk sizes for each such VM? Could it be done by adding an additional disk? 

Thanks,
