After creating your server, the first thing you will want to do is become an administrator (OP).

1. To do this, first connect to the lobby and then to the game server with your Minecraft account.
2. Now open the command prompt from the lobby options: Options>Persistent server>Execute a command
3. In the command prompt window, enter the command "op yourPseudo" then validate.
4. You are now a server administrator and can use all the commands authorized by your new privileges directly from the game chat: https://bukkit.gamepedia.com/CraftBukkit_Commands

When a server update is available, you are notified directly from the lobby activity logs.

To update your server, you will first need to create a new dedicated server on RomStation. Your new server will indeed be created by default in its most recent version.

Then all you need to do is import the data from your old server. So start by stopping your two servers from the lobby options: Options>Persistent server>Stop the server

From the old server lobby, open the file manager (FTP client): Options>Persistent server>Open the file manager

In FileZilla, copy locally this directory "/minecraft/world". From the new server lobby, open the file manager to transfer the previously copied directory. If you customized the "/minecraft/server.properties" file, manually reproduce your changes.

Make sure that the data are correctly transferred before removing the obsolete server. And don't forget to restart the stopped server.
