Since the world will be reset, we will have a new world map. That means that if you want your base to be moved to the new world, send me (Numbers) a private message here on the forums with the coordinates. Then i will personally come by, destroy all chests (i will use worldedit to remove them) and save your home as a schematic.
As always,
-Duke Steam Numbers
disclaimer
Numbers is not to be hold responsible for any missing parts of burried bases. I try my best to get all of it but it's pretty hard when it's underground. To prevent this please dig around it and mark the corners. Also it'll be cut out so you won't be using it afterwards.
