How easily would an FTB Ultimate world made in 1.4.7 convert to 1.5.1? I know that 1.5.1 adds vanilla world gen in the form of quartz, but I'm not too concerned with that. Are there any mod-related things that would be negatively affected by this conversion?

Basically, I made the mistake of searching for a seed for a new world a few days ago, and now I'm excited to start my new world on this new seed. If the repercussions of the conversion would be too negative, I could wait, but if it's nothing severe I'd really like to get started right away.

1.5 will be a Beta and have different world gen. You'll be better off starting a new world since there's no guarantee of successfully converting, nor how long 1.5.1 will be in whatever form it gets released. Heck I believe even using it on a new world is at your own risk. Just start fresh and don't get too attached, that's what happened to some people in the 1.4.2 Beta.

My point was that if he tried to update an Ultimate map right now he would loose all his RP2 stuff. That may not be negative to you, but it might be to him.

Edit: Also he might have weird changes in his world gen in unexplored chunks just past the ones he has explored. As in a half created volcano and such. I do not wish to argue this with you though.

Edit2: Please read my post below.

Before you try anything, make sure you have a backup of your world. There are some mods that, at least initially, will not be in the pack. Unless they are updated before the pack releases (supposedly within hours), they will include: PetroGen, RedPower, Soul Shards, Wireless Redstone, Reliquary and Xycraft. Secret Rooms, IC2, Railcraft and Extra Bees are in beta, so may or may not be included. Mods that introduce world-gen that I know of being added are Tinker's Construct, Natura and Ars Magica.
So, just think about whether it might be best to just create a new world. :)

ShameWillFollow I read your post as you wish to start a new map in Ultimate 1.4.7 and almost immediately upgrade to 1.5.1 If this is not the case and you wish to upgrade when the pack goes to 1.5.1(2) or 1.6, whenever Eloraam get around to upgrading RP2, then I apologize. If you wait for the pack to update itself then you will have little to no issue with the upgrade.

That is correct. I'm very tired with my current world and want to start a new world ASAP. Frankly, I'm a bit impatient and would really like to create this new world now and upgrade to 1.5.1 as soon as it is released, but I was unaware what repercussions would come with it.

so huge gaping holes underground where marble used to be, holes where gems used to be, holes where tungsten and nikolite used to be, all creating air blocks that needs to render the blocks next to it, thereby increasing lag, aaand half formed volcanoes isn't a negative effect? Right, okay, whatever you say Doc!

Blocks are the hello world of minecraft modding. Replace them with blocks of the same block id.

So lets say you've been exploring and loading chunks, and some of that includes say... 3/4 of a volcano, the last 1/4 didn't get loaded. You go to 1.5 and replace all of that basalt stone with, lets say MFR darkstone. You keep exploring.. oh... what's this... 3/4 of a volcano that will never be finished, no matter what block ID tomfoolery you do.

Either never visit that area again, ignore the weird wall, or mine it out and fix it. Better than rebuilding your buildings and infrastructure that you don't want to redo. Some people don't want to climb the tech tree over-and-over again. I play on my own private server now because I can't look forward to doing everything a third+ time. I used MCEdit to trim my world down to what I was using when I switched from Vanilla to Mindcrack, I have some interesting terrain borders already (And a serious set of Thaumcraft dead zones). I don't know if I'll try to re-trim to about the same edges or just move forward. At the very least, I'll try to find a way to mass convert block ids for the gems from the RP ID values to the GT values in the save. I'll need to use my wand of equal trade on a few buildings... Unless RP2 comes out or somebody makes a world gen/item placeholder mod.

The official word on updating the packs stated that there won't be an immediate update until 1.6. The 1.5.1 Pack will be a Beta and not recommended for existing world. In other words there's no rush for you to start over and there's probably no need for you to do so when 1.6 comes out.

The Beta is to whet the appetites of people wanting to benefit from new content in existing mods, new mods, and vanilla. So essentially the 1.5.1 pack isn't even intended to be used with existing worlds.

Yeah, cuz that kind of thing never happens without changing mods around. Hell, it happens in vanilla.

It's just something you get used to playing Minecraft, or you stop playing. Or you pull all your hair out and scratch the bugs out of your skin before being carted off to the padded room.

Unfortunately, I am in a rush to start over. I'm very tired with my current world and would like to start a new one right away. Judging by the responses from people, it sounds like I should only create this world once the 1.5.1 Beta is out.

It won't be out, that's the official word. There's a DIY pack thread on the forums so I'd suggest going that route. I'm going to delve into it myself
