How to Reset the Nether or End Without Resetting the Overworld

Direct answer

Dimension resets delete explored terrain and structures inside that dimension. Identify the exact Nether/End save location for your server type, create a full backup and stop the server before making changes.

Recommended procedure

1. Confirm whether you want Nether, End or both, and tell players items and builds in the affected dimension will be lost.
2. Stop the server, then copy the complete world and related dimension folders off-host.
3. On typical Vanilla saves, the Nether uses DIM-1 and the End uses DIM1 inside the save; common Paper layouts use sibling dimension directories.
4. Rename only the intended dimension data to an archive name and start in staging, never delete all folders based on a generic tutorial.

What to do next

Clear or recreate linked portals carefully; plugin-managed worlds and custom dimension instances may have different ownership and storage locations.

How to verify the result

Visit Nether and End after reset, check Overworld builds and player inventories, and verify portals lead to the intended new terrain.

Version and compatibility notes

Older Paper/Spigot and current builds may use different folder structures. Directly deleting world_nether without verifying the active level name can erase unrelated saved data.
