As a PS3 player trying to find out what I need to do to upgrade to the PS4 version for Stormblood I've found there are some things I don't fully understand.

In order to get my current saved cross hotbar & macro setting to be useable on PS4 I need to transfer my save data by hitting the button in the corner of the ps3 launcher window, and then doing the same in the PS4 launcher window.

But what I can't figure out is if I have to transfer the data before I do the PS3>PS4 upgrade process or after.
