How do I change or downgrade the Bedrock version (e.g. to 1.18) without losing my world?

You can change your Bedrock server's version without wiping your world — as long as you are careful, especially when downgrading. This article explains how and what to watch for.

Setting the version

Set the Bedrock server version on the Software page (open it from the Version chip at the top of the console). It pulls the matching bedrock_server binary for the version you choose. Your worlds/ folder stays in place as long as you do not wipe it.

Downgrading safely

Downgrading carries the same world-compatibility risks as Java, so take precautions.

1. Back up first — Back up now on the Backups page, or download your worlds/ folder via Files/SFTP, before changing anything.
2. Set the target version (e.g. 1.18) on the Software page.
3. Be aware a newer world may not open on an older Bedrock build — a world last saved on a newer version can fail to load after a downgrade.
4. Match your players' client version so everyone can connect.

Warning: Always back up before downgrading. If the older binary cannot read a newer world, your backup is the only way back.

Frequently asked questions

Will I lose my world when I change versions? Not if you leave the worlds/ folder in place. Changing the binary does not wipe the world by itself.

Can I always downgrade cleanly? No. A world saved on a newer Bedrock version may not open on an older build. Back up first, and expect possible compatibility issues.

How do I avoid connection problems after changing? Match the server version to the version your players are running on their clients.
