After announcing last week that the PlayStation 3 version of Final Fantasy XIV will end service in summer 2017, Square Enix has begun the free PS3 to PS4 upgrade program for players. Available until December 31, 2017, the upgrade is done through Mog Station and anyone with a currently expired subscription will be given 14 days of free play.
As Square Enix adds, the upgrade process cannot be undone, all service account data (including characters and in-game items) will be carried over to PS4, and, to register the PS4 code, you must sign in with the same PlayStation Network account you use on PS3.
Here’s everything you need to know about the FFXIV PS3 to PS4 upgrade:

Campaign Period – From Monday, October 17, 2016 to Sunday, December 31, 2017 Purchase of the PlayStation 4 version is not required to upgrade. Please be aware that after transferring to the PlayStation 4 you will be unable to play using your current copy of the PlayStation 3 version.
Please note that after completion, the upgrade process cannot be undone.
Upon completing the upgrade process, a PlayStation 4 system will be required to play Final Fantasy XIV.
All Final Fantasy XIV service account data including characters and in-game items will be carried over upon upgrading to the PlayStation 4 version.
Users who wish to play on both the PlayStation 3 and PlayStation 4 until service for the PlayStation 3 is discontinued must purchase a separate copy of Final Fantasy XIV for the PlayStation 4.
