    1.) Stop your server (if online).

    2.) Go to your world files: https://aternos.org/worlds/ and click on "Files"
    3.) Open the "playerdata" folder.
    5.) Download your playerdata file <Old name UUID>.dat (ignore any .dat_old files).
    6.) Find the UUID for your new name:     https://top-minecraft.com/tools/offline-uuid.php
    7.) Rename the downloaded file on your computer from <Old name UUID>.dat to <New name UUID>.dat
    8.) Upload the file to your playerdata folder (confirm replacing the file).
    9.) Start your server again.
