This guide explains how to update any of our Premium setups from 1.21.8 to 1.21.11. If your setup is currently on 1.21.8, this is the guide you should follow.
Update released: 07th February 2026
Start by downloading the latest version of the setup you are using on BuiltByBit.
Before completing all the step below, please STOP your server to avoid any file corruption!
1. Updating the JAR
The first step is to update your server JAR. We recommend using Paper, so make sure to update to the latest 1.21.11 version of PaperMC: https://papermc.io/
2. Updating the Plugins
The next step is to update all plugins in the setup. The easiest way is to download the latest version of your setup from BuiltByBit. Then, delete the existing plugins on your server (except for any you added yourself) and upload the plugins from the latest setup version.
You also have to update all dependencies.
