I have a question regarding how server maps work with patches. I used to own a server but whenever a new patch came out that changed the world, i had to do a map reset or the map wouldn't work. What i was wondering how you can preserve what you create in your world and transfer it to the new world with ease. I know that world edit copy and paste work but that usually is inconvenient and causes mishaps. Also i know that really popular servers that update their map also preserve what they built so I'm wondering how you do that. 

Thanks!
