I was going through this problem as well I used a USB to transfer them over.(You may be able to use the Cloud as well.)
I used this site
http://www.ign.com/wikis/playstation...sfer_PS4_Saves
It helped me alot. I would suggest not starting a new career on your ps4.
As you may have problems getting your other Saves to copy over.
(Happened to my PG, he is still stuck on my brothers PS4 and unable to be copied over.)
