EPO Policy incremental update manually.
I have a requirement to deploy EPO in zone where internet is not there. So Ihave plan to deploy extra.dat file manually.
But whenever we deploy extra.datfile the updates will be very big so is there a way I can download incremental extra DAT file and deploy through EPO

If I understand correctly, you are talking about an "airgapped" ePO server - where ePO cannot reach the internet to download the DAT files. If this is the case then it's actually the full DAT set that you need, not an extra dat: extra dats are usually small, and only for a particular threat.
To get the full DAT set for an airgapped server, please download the "DAT Package For Use With McAfee ePO" package from the Product Updates page at http://www.mcafee.com/apps/downloads/security-updates/security-updates.aspx . You can then check this package into ePO as if it were a product, and it will provide the full DAT and all the incrementals for your client machines.
