I have several questions about the ps3>ps4 upgrade campaign.
1.) Do I have to finish the upgrade process and download the ps4 version on the ps4 before I hit the "transfer character data ps3 -> ps4" button in the corner of the launcher on my ps3? Or will it be too late to transfer my data that way since once I upgrade to ps4 I won't have a ps3 licence for ffxiv anymore? (not sure if a ps3 game license is required to upload ps3 save data from ps3 to the server)

2.) If I am able to hit the button & transfer the character data before I complete the upgrade to ps4, will I be able to play the ps3 version normally until I'm finally able to upgrade? (don't have a ps4 at the moment because I can't afford it until my birthday in may)
