PS3 to PS4 migration is permanent and can't be undone
If you are a fan of the game Final Fantasy XIV on the PS3 and you own a PS4 game console as well, some good news has surfaced for you. Gamers who own final Fantasy XIV on the PS3 can now transfer their characters, progress, items, and other gear to the PS4 at no cost reports VG247.
That means you don’t have to buy a new version of Final Fantasy XIV for the PS4, you can just download the software and transfer your content. The catch is that once you make that migration, there is no going back. If you want to play the game on the PS3 again, you will have to buy a new copy of the game.
Upgrading your account to play the game on the PS4 requires that you tie the PS3 build to your Final Fantasy account in the Mog Center. The game will make a full launch on April 14 for the PS4. Gamers that didn’t have the PS3 version can buy a retail version then.
FF14 has been in open beta for about a week now testing the game and the servers. The content and progress made during the open beta will carry forward according to Square Enix since the beta is on game servers.
It's worth noting again, that once you start the transfer you can’t undo it. There is no need to rush to transfer your game data to the PS4 if you are still playing on the PS3. Gamers have until December 31, 2014 to transfer the data over.
