Saw this on the Lodestone, wasn't sure if anyone had posted it yet on ZAM. Hopefully it's some good information for some people =)
Transferring Character Data from Version 1.0 (08/15/2013)
Version 1.0 character data will be transferred to FINAL FANTASY XIV: A Realm Reborn (hereafter referred to as FFXIV: ARR) starting from beta test phase 4.
This data includes all characters from Version 1.0 as well as the items they possess.
* Please note that some items have been modified or removed to conform with system changes in FFXIV: ARR.
Starting in beta test phase 4, players logging in with characters from Version 1.0 will be allowed to change their character's appearance.
All aspects can be altered, including race, gender, and name. Please note that changes can only be performed once.
* You cannot select a different World.
Appearance changes made to existing characters during beta test phase 4 will carry over to the release version.
* If you do not change the appearance of your character upon first logging in, you will not be given another opportunity to do so.
* If you should exit the character editing menu before finishing, you are allowed to resume changing your appearance.
* Version 1.0 characters that share the same name may be required to change their name based on the guidelines outlined on the Lodestone.
