How to Change Minecraft Software and Version

In the web-panel, there's a side panel on the left of your screen. Under the MINECRAFT section click on VERSIONS.

Steps

In the VERSIONS page you'll view the following information:
The current software and its relative version being run on your server.

Other software divided in various categories, select any one of those.

You'll find yourself in a page where you select the desired version of so said software.

After you select the version for the software, you'll be asked to tick two options (both optional):

• Wipe Server Files.
• Accept Minecraft's EULA. (Recommended)

After ticking the desired options, click Install on the bottom right of the prompt.

The last step is to restart the server.

Common Issues:

• Downgrading: Switching from a newer version to an older one is not recommended as this leads to World Corruption.
