Summary:
Per [this comment on the issue](https://github.com/facebook/react-native/issues/20710#issuecomment-414631827):
> Babel by default tries to find .babelrc files to configure itself, and once it finds the one from the RN app (which links to the RN preset that only works on Babel 7) it fails.
> The easiest patch to fix this issue is to add babelrc: false to the babel-register method, so Babel does not read any additional .babelrc file.

Summary:
The upgrading process based on Yeoman is a pain. For each file, Yeoman (or the brand new copyAndReplace solution a477aec) compares the newly generated content with the existing one and prompts the user if it differs, with very basic options: overwrite or skip.
I have digged into this problem and came with [rn-diff](https://github.com/ncuillery/rn-diff) (you may have read [this article](https://medium.com/ncuillery/easier-react-native-upgrades-with-rn-diff-5020b5c3de2d#.llvy2dym5)). This repository helps people to upgrade RN on their projects. An alternative upgrading process using `git apply` instead of Yeoman is described [here](https://github.com/ncuillery/rn-diff/blob/master/USAGE.md).
This PR is the integration of this process into the core. I got rid of the drawbacks mentioned in the link below in order to make it a clean, elegant, one-step operation.
This process is based on some Shell operations that:
- Generate the blank sources of both old and new versions
