How to change a terraria server world size

A world size can't be changed, but you can generate a new world for your server with the desired size by changing your server settings.

To change your world size, you will need to create a new world since the one that has been generated used the default size (small).
Follow these instructions :

Stop your server
Go in /saves/Worlds folders
Delete the server world files (world.wld and world.wld.bak files)
Change the size in the "settings" page
Go back to the manage page and click "restart"

Warning : Medium world size and above will require at least 2gb of ram to start properly.

Reading is fine. Running one is better.
