Reusing maps between mod updates

[tacgnol06]

Pardon the noobish question, as I'm new to running a Minecraft server, but is there a way to update my server's map when Voltz updates?

I ask because I'd like to update from 1.1.2 to 1.1.3, but when I load up the map some of the Electrical Expansion blocks have borked textures. Thanks.

Edit: 70 views and no one can tell me one way or the other, eh?

There is no real way to 'update' the map, and oftentimes releases of Voltz requires a new map to be generated.

That's the short answer.

The long answer is, that while not officially supported and bound to cause trouble eventually anyway, in a roundabout manner you can run various tools to update block IDs and entity IDs after having updated, which should correct some of the issues you are seeing. For example, people keeping the 1.0.13 generated maps while upgrade to 1.1.0 found that all the Uranium Ore had been magically transmuted to Blast Compressors. This is basically a fix to IDs that needs to occur, since they changed between the releases and otherwise invalidates the map in various ways.

The reason this is the long answer is because entity IDs would also have to be changed since it isn't just the blocks that changed: Players inventory items would all be screwed up nicely as well.

So there you have it... Update the map easily? No. Make a Frankenstein attempt to correct some of the issues and get the map to at least load and maybe be playable? Sort of -> yes.

Assuming you have ID changes figured out, actually upgrading your server without resetting the map requires you to remove some of the old files. I recommending moving them to a backup location in case something goes wrong.

For upgrading any modded server, I would recommend following these steps:

1. Create a new folder to hold your backup. If you are running a server on your own computer, this folder can be anywhere. If you are using a host, you have two options: (a) Using a FTP client (I recommend FileZilla), create a new folder on the remote server for the backup, or ( Using an FTP client to download the files from the server to your computer.
   
2. Copy the /mods, /coremods, /mods, /config, /world, /world_nether, and /world_the_end folders and the server .jar (Voltz.jar) to your backup location. If the server is running on your own computer, you can simply copy and paste the folders. If you are using a host, either use a FTP program to copy them to the folder on the server you created earlier, or use the FTP program to download the files to your computer.
   
3. After making your backup, delete the /mods, /coremods, and /config folders, and the server .jar.
   
4. Download the latest version of the modpack you wish use. After extracting the zip, you should see three folders (/mods, /coremods, and /config) and one file (in this case, Voltz.jar). If the server is running on your own computer, simply copy and paste the files into the folder with the rest of the server files. If you are using a host, use a FTP program to upload the three folders and the file to your server.
   
5. All done! Your server should be upgraded. If anything goes wrong, just delete the files you backed up earlier (/world, /mods, etc.) and copy the old files back into their original location.
   

Hopefully this is helpful. Feel free to share this with anyone else who needs help.
