So I have a brand new ps4 sitting in front of me, but before I hook it up and go through the upgrade process I wanted to find out about some information. I heard that the upgrade process is complicated and you lose all of your hotbar settings and other things after the upgrade.

1. Is it true you lose your settings, or is it possible to keep your settings by copying the character and settings save data to a USB drive from ps3 and then plug the USB drive into the ps4 and transfer those saves to the ps4? Or is that not possible since the character and settings save data (2 separate files) is saved as a ps3 file for ps3 version?

2. I know I go to Mogstation and click that upgrade button, but how does the process work beyond that? Is there anything I should know ahead of time? I'm already aware I can't go back to ps3 version, and the info in this link. http://na.finalfantasyxiv.com/pr/ps4/ps3_users/ Anything beyond that? That makes it sound simple, but I always hear it's a pain. Is that because of what I mentioned in 1.?
