You just need to have the server generate new chunks, just by going pack where you have explored before. BUT this looks bad since the world generators changed from 1.7.
You can use MCEdit to take a schematic of your old work and paste it into a new world that is 1.1
I have a small server that i use for myself and a few friends.
I have heard tell that the only way to get chunks to update, say, from 1.0 to 1.1 is to delete the world and create a new one.
Is this correct, or is there any way to force the already created chunks to update to 1.1?
The majority of the chunks in my server are in 1.7 mode, and i'm missing the 1.1 goodness.
Cheers for any and all help.
