Version 1.12 of Minecraft was first rolled out in June 2017, followed by version 1.12.1 in August, and version 1.12.2 this September.
This latest version is an update for Minecraft: Java Edition and is not compatible with servers 1.12 and 1.12.1. It brings one change and several fixes to the older version only known as Minecraft.
So if you are looking to upgrade to version 1.12.2, here’s what you need to do.
How to update Minecraft
- Start the Minecraft Launcher.
- Look for “Options” next to the username textbox, and click on it.
- Once the “Launcher Options” window open, click on “Force update!”
- Click “Done” when prompted.
- Login to Minecraft using your credentials. This will initiate the update.
Note that you will lose your mods when you update the game since they are saved in the minecraft.jar. So make sure to back it up.
How to back up minecraft.jar
- Click “Options” in the Minecraft Launcher.
- Right behind “Game location on disk”, look for Path and click on it.
- Open “bin” in File Explorer to find minecraft.jar.
- Copy it to another folder in another location, such as Minecraft Backups on desktop.
Remember to create a subfolder within the backup folder and label it to the version you are backing up. Since you are updating to 1.12.2, label the folder 1.12.1, which indicates that the minecraft.jar saved is under the older version.

In the event that you are unhappy with version 1.12.2, you can always restore to the previous version. Make sure you have a backup of the minecraft.jar of the previous version or a Pre-Release.
How to restore to previous Minecraft versions
- Have a copy of the previous minecraft.jar / Pre-Release ready.
- Look for the new minecraft.jar in “bin” in File Explorer.
- Delete the current copy and replace with the old minecraft.jar version.
Make sure the file is named “minecraft.jar” or “minecraft”. If it only appears as .jar, rename as recommended.
If you plan to do a fresh install, follow the procedure in updating to a new version.
With your Minecraft updated, time to start testing the new platform.
