How to change your MC Version

First, head over to https://mcutils.com/server-jars. This is where we will download the server JAR file. Once you are there, choose your desired flavor from the "Type" category. Then, select the version you would like to use. Once you have filled in both fields, click the "Download" button. A .JAR file will be downloaded to your computer. Once you have the file downloaded, head over to https://game.owehost.com/. Then, find your server and make sure it is offline. Once it is offline, go to the "Files" tab. Once there, find a file named "server.jar" and delete it. Then, upload the .JAR file you downloaded earlier to your server. Then rename the file you just uploaded to "server.jar". Next, start your server. If you get any errors, this could be related to your world files, as Minecraft worlds change each version.
