How to change server version
There are two ways to change your server's version.
First option
Using our built-in version changer.
- First, log in to the game management panel. Then open up your server.
- Next, head over to More Options from the nav bar and click on Versions. This will open up the version changer.
- Once you're there, just click on the version you want to switch to. It will then show all available builds for that version (e.g., Paper → Paper versions).
- Now click on the specific version you need. It'll ask whether you want to keep your server files or wipe them. Choose your preferred option, then click Install.


Second way
This is the manual method.
- First, visit https://mcutils.com/server-jars and download the server version you want.
- Then upload it to your server using the File Manager.
- In your server files, look for a file named server.jar and delete it. (If you don't see it, you can skip this step.)
- Now rename the newly uploaded file to server.jar, and then restart your server.

Note
If you're downgrading your Minecraft version (e.g., from Paper 1.21.4 to Paper 1.20.4), make sure to delete your old world files (world, world_nether, world_the_end). Otherwise, your server might crash due to world corruption.
