How to not have to have a map reset for 1.3?

Hello, I have a server, and I would love to keep my map. My map border is at 5,000, and I would hope that I could keep the map while implementing the new items? I'm assuming the new ore won't take effect untill 5000+ if I'm correct? Please help

 

you dont need one.

EDIT: Unless you want the new stuff.

 

This doesn't help at all.

 

the new villages and emerald wont spawn in existing generation.

 

just extend out the map border by like 3000 or someting like that to get new terrain

 

If your border is at 5000 and you have only explored 2000 or even 4000 blocks out then after 3000 new areas will spawn. New areas spawn in chunks. It would just mean your players have to go further for the "new stuff". You don't have to extend you boarder if you didn't explore up to that 5000, but if its all loaded then I think you need to expand it.

 

you can also use worldedit to regen generated chunks (don't do this in places where stuff is built!)

> make selection
> //regen

You could load the map into a program such as McEdit and deleted all the chunks that have been explored but have nothing in using the delete chunk function and when you reload it back into your minecraft server, when you re explore the chunks you will have all new terrain features.
