I have a server running the standard, unmodified Vanilla server on a Linux box. After talking to the people on the server we have decided that moving to a Bukkit Server would be better because of the awesome plugins.
However, it seems that Minecraft generates "nether" and "overworld" files differently than Bukkit. Bukkit generates a world and a world_nether folders. I have read the forum post that copying the Vanilla's world folder to world and world_nether seems to work but I feel like this a a bit hackish and might cause problems in the future.
Has anyone successively done this?
