Upgrade to the new SE+K2 integration

There is a new integration between Krastorio 2 and Space Exploration being worked on. It is possible to upgrade a save, but changes are required. The purpose of this page is to help understand what will break when updating. If you have already played SE, and maybe SE+K2, there will be situations that at first look like a major mechanic is broken. This is probably not the case however, you just need to analyze the options and plan accordingly. A few recipes have changed considerably. So much that old ways of playing don't work anymore. This game is no longer the same, so you need to be mentally prepared. E.g. making solid rocket fuel from Vulcanite is now a slow and expensive process requiring more resources.

Dependencies
Krastorio 2, version 1.2.4

Technological tree
The technological tree has major changes. That means that you may have to research something again. But no entities will be removed.

Pre space
It is easy to upgrade the save if you haven't started with the space sciences.

Inserter recipes are updated to combine the AAI Industries recipes with the K2 recipes. Specifically, each recipe takes as input the previous lesser type of inserter.

Later part of the game
The Advanced Tech Card recipe takes Bioscrubber instead of Big Electric Motor, as well as the Pylon and Space Platform Plating.
