Changing the Minecraft Version

Back up first

We highly encourage taking a backup of your server before switching versions. Data may be lost, and going back to an older version is not supported and will cause world corruption.

Update the Minecraft Version field

Navigate to the game panel and select your service, then go to the "Startup" section and locate the Minecraft Version field.

Set the new version

Replace the Minecraft Version value with a valid server version, for example 1.20.4 or 1.16.4.

Reinstall your server

Navigate to the settings page and click the Reinstall button to apply the change.

Changing server type

To change your server's software entirely (for example, Paper → Forge), follow the steps below instead.

Delete old files first

Switching software can require overwriting files the previous software left behind, and the install won't always do this for you. Things like server.jar, the libraries folder, and the cache folder are common culprits. Back up anything you need, then delete these via SFTP or the file manager before continuing, otherwise the install may fail or leave old files behind.

Open the Software section

Navigate to the "Software" section of the panel.

Select and confirm

Select the software you want to use, click "Change Version", ensure the "Reinstall Server" toggle is checked, and press "Change Version".
