SFTP Method
Stop Your Server
That is to prevent conflicts during major operations such as world changes.

Select all the world files you wish to replace and delete them
That is usually world, world_the_nether and world_the_end
Rename your custom world folder to world (capitalization matters).
Upload the world file from your Local Storage to SFTP.
Start Your Server
Start the server back up and you are ready to go!

There you go! Now you know how to upload your own Custom World!
