(adsbygoogle = window.adsbygoogle || []).push({}); I want to transfer all my save data utility (e.g black ops 2 online level) to a different PS3 and different user,would this work?

your online level is stored online?

Yes it will work but u cant transfer ur online stats ( rank ... ) its not saved on ur ps3 its saved on a server
Just connect ur ps3 and the second ps3 with a ethernet cable a random one nothing special
And then do data transfer u can find it on ur ps3 in the system settings

Then all will tranfer ur game updates saves ur accounts all

Not a crossover cable.
