Ps4 game upgrade on two consoles ?

I have two ps4s mine and my sons I've been playing my ps4 since launch and did the £10 cod ghosts upgrade. So my son won't be opening his ps4 till Xmas can I share upgrade with his ps4 or do I need to buy it again, we both have a copy of cod ghost ps3 on disc it's just the upgrade im not sure about. I know we can both share my ps plus.

Any1 ?

if i am not mistaken you can activate your account on the second console, then download and install the games you have bought... i am not sure if you have to select it as you primary gaming console though...

on the other hand, if you have bought the disc version of the game, theoretically, you will not be able to play simultaneously since the disc needs to be inserted while playing the upgrade (or so they said)...

I have two ghost discs and two ps4s so if I can download the upgrade on the 2nd ps4 it should work on both right ?

Downloads are tied to a single PSN account which can be activated on multiple systems, so if both PS4's are tied to the same account then you can use the download for the other PS4 at no extra cost as it is now paid and in your download list.

This applies to all PS Store content I believe.

@voodoocanzo:

i seriously don't know but theoretically it should be ok... :)

PSN content is locked to 2 different PS3 in the past, it used to be 5 but they changed when they realize people were exploiting it.

So yes, theoretically it should work fine.
