Under the Zone Copy/Import tool.
I like to go through and change a lot of the IDs on the things it imports (grid, npc_types, spawngroups, etc), but it imports a fully working copy of the zone.
Note that you'll also need to set faction and loot tables after import, but this is a couple clicks to get started.
