Will changing version delete my progress or keep the same map?

Changing your Minecraft version swaps the server software, not your world. Your map, builds, and data stay right where they are. The one thing to watch is downgrading, which can be rough on a world that was saved on a newer version.

What a version change actually touches

The Software page reinstalls the server software while keeping your world; any files it replaces are moved to a _previous folder. Your map simply loads on the new version, as long as it's compatible.

Keeping your progress safe

1. The Software page reinstalls the software while leaving your world in place.
2. Your map loads on the new version as long as it's compatible.
3. Take a backup first — Back up now on the Backups page, or a copy via Files or SFTP — so you can revert if a plugin or mod isn't ready for the new version.

Warning: Upgrading is usually smooth, but downgrading a world to an older version can corrupt it. Back up before downgrading especially.

Frequently asked questions

Will I lose my builds? No — the world is untouched by a version change.

Will my plugins stop working? They may need updating to match the new version, but your world data is safe regardless.
