Final Fantasy XIV PS4 transfer

Hello.
 
So my girlfriend is wanting to move to the FFXIV Gil PS4 due to her laptop not being able to handle the game too well, and come heavenward its just gonna burn out.
 
i have a few questions which support aren't really making too clear for me.
 
1. We made a new SE account to do a free trial on the ps4 to test the game, is there a way to untie that free trial account from her main PSN account to then tie her PC account to it.
 
2. How would we go about doing this license transfer? i know it involves buying a new copy of the game, would we put the code in the mog station or?
 
3. Any other information you can give would be appreciated
 
1. I'm not sure, but I think there might be. Have you tried googling it?
 
2. Use the code at the mog station.
 
3. All character info will be transferred to the PS4 version, however you're going to have to reset your gear sets, system and character configs, your chat tabs, and of course your skill sets. All of those will be completely lost upon upgrading. Luckily everything tied to your character you keep, including FFXIV Power leveling what you're currently wearing.
