Ok to uninstall current version ?

[Delsus]

The A Realm Reborn client is completely different from the current version, so it's fine to uninstall the game if you'd like!

However, please keep in mind that it will be possible to import your current character data to the ARR character creation benchmark to play around with. So if you'd like to do that, be sure to back up your FFXIV folder located in your My Games > FINAL FANTASY XIV before uninstalling.

Thanks for this Rukkiri, I had no idea that we can import our characters into the ARR benchmark, I will make a backup now.

And it's nice we can uninstall the client when we are done
