You can't go back to PS3 version after.

Hope this helps.
What exactly does "all your data" mean? hotbar setup? system config and character config settings? macros? Have you yourself or anyone you know tried copying the settings to a USB device beforehand and then transferring to ps4? So I use the code while on the ps3?
