Subscritpion on console questions.

[eridian]

Ok, so i got the game when it first came out and i got it on ps3. I reached end game and maxed out a few jobs and since the character pop ins were so bad on console it made it impossible to do large world events on it. So i decided to wait to get a ps4 to play it on there. These are my questions. First do i need to buy the game again to play it on ps4 if i already have a disc copy on ps3, second can i use my same character, and third how do i renew my subscription if i play on console, is it the same as if i play on pc?

Also, I cannot use credit cards or debit cards since I don't have either. So can I get game cards to us instead? Or would pre paid visa credit cards work to put in a sub?
