Greetings! I changed my username in the official Minecraft website, and I'm using the official launcher. So I have a question regarding the steps Roman sent. He sent these following steps:
• Take a backup on the backups page
• Download the world
• Find out your UUID
• Rename your old UUID with the new UUID
• And upload the world
So once I make a backup and download the world, what happens to the original world, do I have to delete it? I'm confused
Thanks!
