Feature Request: Native Tool to Transfer and Merge Builds into

Subject: Feature Request: Native Tool to Transfer and Merge Builds into New Worlds During Biome Updates ​Dear Mojang Team, ​With every major update introducing exciting new biomes and terrain generation, long-term players face a frustrating dilemma. Existing worlds feel legacy, and players cannot natively transfer their homes, redstone machines, or custom structures into newly generated maps to experience the new features. ​To improve the long-term player experience, I would like to suggest the following features: ​World & Structure Merging Tool: An official in-game tool that allows players to select specific structures or regions from an older world and merge them seamlessly into a newly generated map. ​Smart Coordinate & Height Alignment: A selection system that transfers builds based on coordinates with automatic elevation adjustment, ensuring structures sit naturally on the new terrain rather than floating in the air or being buried underground. ​This feature would allow the community to explore brand-new world generation without losing years of hard work and creativity. ​Thank you for your dedication to making Minecraft better with every update!
