Is it possible to transfer all pb updates to new playbook?

Hi,
I have two 32 GB playbooks. One is updated to OS 2.1.0.1917. The other one I am about to open up and it will need to be updated. My internet has limited data. Is there a way to transfer all the updates from one playbook to the other, instead of using the wifi, internet. If so, how would I go about doing this? Drag and drop? Copy and paste?
Any help would be appreciated.
Thanks, KL

The whole OS available for download, as for transferring from one PB to another, I do not think it would work as well as you would hope, as a matter of fact, I would safely say no as you would not be able to copy the bar files off of the first PB.

Looks to be at about 500Megs or so.
