Hello everyone! It has been a crazy 2020 so far and I’m way behind on articles, pull requests, issues, etc. But even in these crazy times I do have some good news: the 1.16 Minecraft update has been released and I have updated my Minecraft setup/server management script for Raspberry Pi!
If you don’t yet have my Raspberry Pi Minecraft setup script visit the Raspberry Pi Minecraft Server Installation Script / Setup Guide to get it!
You can change the version here to whatever you want as long as it’s supported by the Paper Minecraft server.
PLEASE BACK UP YOUR SERVER FIRST! The server makes automated backups by default for you in the backups folder but I recommend you back up the entire server folder yourself (basically the entire minecraft folder) any time you attempt to upgrade or downgrade. If you need to roll back to older versions it won’t work without a backup from that version or older!
The easiest way to upgrade an installation is to download the latest SetupMinecraft.sh and run it. This will automatically upgrade you to the latest version.
Upgrading and downgrading to versions that aren’t the default the script chooses is pretty simple. Simply change the Version line at the top in the SetupMinecraft.sh script:

# Minecraft server version
Edit this file in your favorite text editor (you can use nano or vi on the Pi like nano SetupMinecraft.sh) and change the Minecraft version to what you want.
PLEASE RESTORE USING A BACK UP FROM THE VERSION YOU ARE DOWNGRADING TO
If you are having problems on a newer version of Minecraft and want to downgrade you can do so using a complete backup of your server before you ran it on a newer version.
The reason you can’t take server data that has been touched by a version such as 1.16.1 and go back to 1.15 is that the new version adds all sorts of new data types/structures for the new content into your server data files. If you try to roll back the old versions of the Minecraft server will not understand these data types since they didn’t exist in that version and will crash.
As long as you use a backup for your server files from that version (or older) it’s as simple as changing the version in SetupMinecraft.sh just like I show in the “Upgrading” section.
You can upgrade any old version of Minecraft to any version, but again make sure you have a backup first as it is a one way street and you will need that backup if you want to roll back!
