I bought the season pass in PS3 and I downloaded episodes 1-4 (5 wasn´t available)

While I was waiting for episode 5 I bought a PS4 and sold the PS3.

I was wondering if I could recover the data to play the last episode through my Playstation network account and...

I bought the season pass of the game in PS3, do I have to re-purchase the game for PS4? Shouldn´t it be a free download?

Thank you very much,
