How to change version on a Minecraft server
To keep it simple, our panel has a version installer built into it. It has all the most popular jars for Minecraft already built-in.
You can find the version installer under the Server Tools tab.
To install a version, select the version type you want from the drop down. In this case, we'll install Paper. Next, select the version number, in this case we'll select 1.19.2. Then press install. You're all set, everything has been downloaded for you. Just restart the server.
