A simple plugin giving the back end server the ability to move players to different servers.
The ServerSwitcher Plugin is a Bukkit/Spigot/Paper plugin that enables server administrators and other plugins to send players to different BungeeCord or Velocity-connected servers. Since the backend server and plugins on it typically do not have access to the /server command , this plugin provides an alternative method for transferring players between servers using a command and the plugin messaging channel.
/sendto <player> <server> command. /sendto <player> <server> – Moves a player to the specified server..jar file into your Bukkit/Spigot/Paper (Back end) server’s plugins folder. THIS IS NOT A PROXY PLUGIN, IT IS ONLY TO BE RUN ON THE BACKEND!
