How To Change An Aternos Server Version: A Comprehensive Guide

Want to update or downgrade your Aternos server? This guide explains how to change an Aternos server version swiftly and safely, allowing you to enjoy the latest features or revert to a more stable build.

Introduction: Why Server Version Matters

Running a Minecraft server on Aternos offers fantastic flexibility, including the ability to modify your gameplay experience by changing the server version. This version dictates which Minecraft features are available, which mods are compatible, and ultimately, how players interact within your world. Understanding how to change an Aternos server version is crucial for maintaining a vibrant and enjoyable server environment.

Whether you’re chasing the newest Minecraft innovations, ensuring compatibility with specific mods, or troubleshooting server issues, managing your server version is paramount. Aternos makes this process relatively straightforward, but it’s essential to understand the steps involved and potential pitfalls.

Preparation: Backing Up Your World

Before making any changes to your server, always create a backup of your world. This is the most critical step in how to change an Aternos server version. A version change could potentially corrupt your world data, particularly when downgrading to an older version.

Stop the Server: Ensure your Aternos server is completely stopped. No players should be online.
Navigate to Backups: In your Aternos control panel, find the “Backups” section.
Create a Backup: Click the “Create Backup” button. Give it a descriptive name (e.g., “Pre-Version-Change Backup”).
Wait for Completion: The backup process will take some time, depending on the size of your world. Once complete, you’ll have a safe copy to restore if anything goes wrong.

The Process: Changing the Server Version

The core of how to change an Aternos server version involves navigating to the Aternos settings and selecting a new version.

Access Your Aternos Control Panel: Log in to your Aternos account and select your server.
Go to “Software”: In the left-hand menu, click on the “Software” option. This is where you manage your server’s core software.
Choose Your Software Type: Aternos offers several software types, including:
- Vanilla: The original, unmodified Minecraft server.
- Snapshot: Unstable, pre-release versions of Minecraft. Use with caution!
- Forge: Required for running Minecraft mods.
- Spigot/Bukkit: Popular for server plugins.
- Paper: A highly optimized fork of Spigot.
  Select the appropriate software type for your needs.
Select the Desired Version: Once you’ve chosen your software type, you’ll see a list of available versions. Select the version you want to use. Be very careful when selecting snapshot versions as they can be unstable.
Confirm the Installation: Aternos will prompt you to confirm your selection. Note that this process will likely delete your world if you are switching between different software types. If you are simply updating or downgrading within the same software type (e.g., from Vanilla 1.20.1 to Vanilla 1.20.4), your world should be preserved.
Restart the Server: After the new version is installed, restart your server. The server will take some time to boot up as it loads the new version.

Important Considerations: Mod Compatibility

If you’re running a Forge server with mods, changing the Minecraft version requires careful attention to mod compatibility.

Check Mod Compatibility: Before changing the server version, ensure that all your mods are compatible with the new version. Visit the mod developers’ websites or Minecraft forums to check for updates.
Remove Incompatible Mods: If some mods aren’t compatible, you’ll need to remove them from your mods folder before starting the server. Incompatible mods can cause crashes and other problems.
Update Forge: Make sure you’re running the correct version of Forge for the Minecraft version you’re using.

Troubleshooting: Common Issues

Even with careful planning, issues can arise when changing the server version. Here are some common problems and their solutions:

Server Crashes: If your server crashes after the version change, it’s likely due to incompatible mods or corrupted world data. Check your server logs for error messages. Try removing recently added mods or restoring a backup of your world.
World Corruption: If your world is corrupted, restore a backup. Prevention is always better than cure.
Login Problems: Sometimes, players may experience login problems after a version change. This can be due to outdated Minecraft clients. Advise your players to update their Minecraft clients to the correct version.
Plugin Issues: If you use Spigot/Bukkit/Paper plugins, ensure they are compatible with the chosen Minecraft version. Incorrect plugin versions can cause server instability.

FAQs: Deep Diving into Aternos Server Version Changes

Why can’t I find the latest Minecraft version on Aternos?

Aternos may not immediately offer the very latest Minecraft version upon release. This is because they need time to ensure the version is stable and compatible with their platform. Check back regularly, as new versions are usually added within a few days.

Can I switch between Vanilla, Forge, and Spigot servers without losing my world?

Switching between different software types (e.g., from Vanilla to Forge) usually requires a world reset. This is because these software types use different world formats and data structures. It is strongly recommended to backup your world, as Aternos will typically delete it when switching between software types.

How do I find the correct version of Forge for my Minecraft version?

The Forge website provides a list of Forge versions compatible with different Minecraft versions. Always download the recommended or latest version for optimal stability.

What are Snapshots and should I use them?

Snapshots are pre-release versions of Minecraft. They are intended for testing and may contain bugs and instability. Use snapshots at your own risk, and always back up your world first.

Can I automatically update my Aternos server to the latest version?

Aternos does not offer an automatic update feature. You must manually select and install the desired version in the “Software” section. This gives you more control and ensures you can address any compatibility issues before updating.

What happens if I downgrade my server to an older version?

Downgrading your server can lead to compatibility issues. Features added in later versions may not be available, and your world may be corrupted. Always back up your world before downgrading.

How long does it take to change the server version on Aternos?

The time it takes depends on the size of your world and the speed of the Aternos servers. It usually takes a few minutes to install a new version.

Why is my server lagging after I changed the version?

Lag can be caused by several factors, including a large number of players, resource-intensive mods, or an underpowered server. Try optimizing your server settings or upgrading your Aternos server (if that were possible, Aternos servers do not have an upgrade option, rather they are free to use).

How do I restore a backup after a failed version change?

In the “Backups” section, select the backup you want to restore and click “Restore”. This will overwrite your current world, so make sure you’ve backed it up first if you want to keep any changes you’ve made since the last backup.

Will changing the server version affect my server settings?

Changing the server version can reset some server settings, particularly if you’re switching between different software types. Review your server settings after the version change to ensure they are configured as desired.

Can I run multiple Minecraft versions on different Aternos servers using the same account?

Yes, you can run multiple servers with different Minecraft versions on Aternos using the same account. Each server is independent and can have its own settings and version.

What should I do if my server is not starting after changing the version?

Check the server logs for error messages. These logs can provide clues about the cause of the problem. Common causes include incompatible mods, corrupted world data, or incorrect server settings. If you can’t resolve the issue, restore a backup or seek help from the Aternos support forums.
