Migrate an Existing World Into Your MultiWorld Server
Prepare Your World Files
Before importing, ensure your world folder is in the server's worlds directory. The world must be a valid Minecraft world with the standard structure (containing level.dat and region folders).
Import the World
Use /world import <worldname> <worldtype> where <worldname> is the folder name of your world and <worldtype> specifies the dimension type (such as overworld, nether, or end). For example: /world import old_survival overworld imports a survival world.
Verify Import Success
Run /world list to confirm your imported world appears in the server's world list. Use /world info <worldname> to check its settings and ensure it loaded correctly.
Configure and Enable Access
After import, set any desired flags using /world flag <worldname> <property> <value>. Then grant players teleport access with appropriate permissions, and they can join using /world teleport <player> <worldname>. Your existing world is now fully integrated into the MultiWorld system.
