If you're playing on the Deadly Duck SMP, it's always a good idea to keep a personal backup of your map and waypoints — especially before big updates or migrations.
CopyEdit
.minecraft/XaeroWaypoints
Press Win + R
, type:
shell
CopyEdit
%appdata%\\.minecraft\\XaeroWaypoints
Copy the entire XaeroWaypoints
folder to a safe backup location.
(Optional) Do the same for:
CopyEdit
.minecraft/XaeroWorldMap
📦 These folders contain all your saved waypoints and explored terrain for each server and dimension.
When the server IP or domain changes (like moving from one host to another), Xaero’s Minimap treats it like a new server. Here’s how to transfer your waypoints:
Join the new server at least once, and create a dummy waypoint. This will generate the new waypoint files.
