Converting single player Nether to Bukkit

Hey there, I like to play singleplayer adventure maps with a friend of mine on my Bukkit server that I made just for this. The problem is, some of the maps use the Nether as a crucial part to completing them. When I load the map with Multiverse into Bukkit, how do I also load (and link) the world's nether? (If I just go through a portal, Bukkit generates a new _nether world.

Bump?

You have to do /mv import world_nether normal

 

I don't have a world_nether folder... This is a singleplayer world. That's the whole problem, I only have one folder no nether.

 

You can find the nether world files in Applacation Support/minecraft/saves/world/DIM-1/
Or if you have windows open "Run" and type in %AppData% and go into the .minecraft folder
After that,
Open your server folder then
Simply take the DIM-1 folder and drop it in the world_nether folder if theres already a DIM-1 folder in the world_nether folder you can delete or move it somewhere els.

Notes: If your default world name was changed change world_nether for example: "Myworld_nether"
And make sure enable nether in server properties remains "true"
