Updating Pixelmon

This article is outdated, and is no longer being maintained. Information here may no longer be relevant.

The Pixelmon mod is periodically updated to add new features and fix issues with the mod. However, if you have already installed a previous version of Pixelmon, you will not automatically be updated to the newest Pixelmon version when it is released. You will need to manually update Pixelmon to the latest version.

Notes

• This page is for players who have already installed Pixelmon previously. If you do not have Pixelmon installed, refer to the installation page instead.
• This page only covers the updating of Pixelmon when it is for the same Minecraft version as the previously installed version. If you are updating to a new Minecraft version alongside a new Pixelmon version, you should follow the steps in the installation page, since you will need to reinstall Forge for the new Minecraft version.
• When an update for Pixelmon is available, it is announced in the Pixelmon Discord's "#1-12-2" or "#1-16-5" channel.
• It is advised to make a backup of your Minecraft world(s) before you update. World save files can be found in the "saves" folder in the Minecraft game directory.

Server

1. Shut down the server if it is currently running.
2. Download the new version of Pixelmon from this page.
3. Navigate to the server directory and find the "mods" folder where you previously installed Pixelmon.
4. Remove the previous version of Pixelmon from the mods folder.

External JSON files

If your server uses custom external JSON files, you may need to update them if a new version of Pixelmon adds or changes the files. Failure to do so will cause problems if new features rely on the newly introduced changes.

1. Make note of all custom changes you made to the external JSON files.
2. Delete the "pixelmon" folder and restart Minecraft to let the default external JSON files regenerate.
3. Re-add all of your custom external JSON file changes.
