Direct answer
For moderate structures on compatible versions, WorldEdit can copy a selected region and paste it into another loaded world. For large or modded worlds, test a schematic on staging first.
Recommended procedure
- Create an isolated backup of both source and destination worlds and ensure you have WorldEdit permissions.
- Use a selection wand (
//wand) and select two corners of the build, including its height. - Stand at a memorable reference point and run
//copy; WorldEdit preserves the offset relative to your position. - Go to the target world, stand at the intended reference point, preview the area and run
//paste -aif you explicitly want to preserve target air-excluded blocks.
What to do next
For transfer across servers, save a supported schematic file from the source WorldEdit installation and load it in the destination; keep block/data version compatibility in mind.
How to verify the result
Inspect redstone orientation, block entities, containers, NPCs, claims and overlapping terrain before reopening the destination.
Version and compatibility notes
//paste -a skips air, so it may leave unwanted old blocks inside your pasted building. Entities, biomes, inventories and custom mod blocks require special flags or additional handling.
