Update World from 1.2.5 to 1.4.6

[Bobsteru]

I've got an old world we spent lot's of time building a city on. We have tried to not spread to much to avoid unnecessary chunk generation with this update in mind. I've got MCedit but haven't got much experience using it. Are there someone who knows how to replace blocks since the ID changes? Or is there still plans on making a updater that would fix an old world for the new pack?

Any help appreciated. Thanks

use a custom version of mIDas.

use a custom version of mIDas.

How do I do that? Sorry have almost none experience with these stuff. Will all players have to do the same?

[Bobsteru]

Since I believe there are more people than me who want to save their old world I'll post what I found: http://www.mcschematics.com/index.php?topic=1310.0

A post talking about how to replace stuff. Now are there any where a list of block ID changes?

Other wise I'll start compiling a list and post here, feel free to bet me to it ;P

I shall be interested in the progress : which IDs will make my tekkit classic world fail when starting it in tekkit lite ?

[Bobsteru]

If you start up your classic and press e you have a option/settings button in the lower left corner for Nei there you have the option to dump Block Id Map or something like that.

That gives you a txt file with all Ids. Then you load up a new world with your new pack: tekkit lite, voltz or what ever take your fancy, do dump the list from here also.

Then I copied and pasted the both list into a excel(numbers google docs etc) sheet. Then in column c I put the formel to =(a1=b1) That way I got a false on the changes and could sort out the not affected ids and see the changed ones.

Eagerly awaiting for a way to convert my multiplayer worlds, I get an error when I try to use my 1.2.5 worlds with 1.4.6 for my server.

I hope MCEdit works out, I'm going to give it a go right now.

[tntexplosivesltd]

Nope, seems MCEdit doesn't like Tekkit world files. Going to see what differences there are between the 1.2.5 and 1.4.6 worlds

I created a list with all changed IDs. When the new ID is 1 then this means that this Block doesn´t exist in Tekkit Lite anymore. I hpe this will help to convert existing worlds to tekkit lite. I tried mIdas to change the IDs but it doesn´t work, because the programm cannot load the tekkit world file. How can I change the IDs?

Change the tekkit lite IDs to match the old ones.

[darkhoernchen]

But how do I change the IDs ?

And I have to change the Ids in the world folder, not in the config files.

I would love to hear the answer to this question!

Since i have never tried it before and have no clue about, where to do it and how to....

And I would hate to restart with a new server and loose a lot of hours work in that world!

[EzioA]

Change the mod ids, not the world ones!

Ok so I've managed to use my list of changes with mIDas Gold which I found through this thread: http://forums.technicpack.net/threads/how-to-convert-tekkit-classic-world-to-tekkit-lite.34915/

I hade problems with transposer and tanks so I replaced them with an other block and then I changed them back. My advanced machines where wrong id probably so have to change that but I can see the light in the end of the tunnel.
