Did you try the 'Load Open World' option upon connecting to the Server ? ( I have not yet tried it as I do not have our Open World Data )
Otherwise , I would assume it works just like other Dedicated Servers , Connect to FTP ( Server Stopped ) and upload your Local Data to the correct location on the Server & then restart. RocketWorx did mention how to move Prospect Data between Local Hosts in the latest weekly release notes.
I will let you know how it goes for us when my Son gets home from work in about 10 hours ( we live on opposite sides of the world )
