[Westbay]

Let's say I have a map which is 8.0 or 10.98 or similar, how do I go about to upgrade / downgrade it to 8.6?

Open a new empty map goto the main menu select File > Import > Import Map and navigate to the map you want to load
Make sure that the map editor is set to the version you want to use in Edit > Preferences
