Death and I backed up the old world file and converted the server over to 1.8 pre release... we just couldn't wait.  You can get the pre-release here:http://www.minecraftforum.net/news/214-want-to-play-18-early-heres-how/

The jar file you download goes here ->C:\Users\(username)\AppData\Roaming\.minecraft\bin

It will replace your current minecraft.jar

get on mumble if you want/need help.  We will decide later if we want to switch back to our original world or start over...
