Nah. I'm not going to destroy it all.
There's a few possibilities. The first is that I move the current worlds to a powerful but unreliable backup server I happen to have, and then put the new world on our server.
The second is to take both current worlds offline and offer them for download, and then reset with the new world.
The third, of course, is multiversing all three worlds, but as I said I don't think our server can handle that. It may be worth a shot.
The fourth is to move all of UboaCraft to the more powerful server, but I'm not sure how long I'll have access to it, so UboaCraft could disappear suddenly in the future.
That said, UboaCraft is currently down and I'm not sure when I can bring it back up, due to time constraints and other issues. (It will take several hours to set it all up most likely.) This weekend is a possibility, though there's quite a few plugins that haven't updated for 1.3.
And of course, hosting UboaCraft is very expensive. Based on how much funds we pull in through donations and such, it either will or won't be shut down completely near the end of next month, so we don't lose all of Uboachan instead.
