What is the Easiest Way to Update React Native?

i have a large project writing js, now i need change to typescript this is a big challenge

Expo also makes it easy: <a href="https://typescript.tv/hands-on/upgrading-expo-in-a-react-native-project-with-typescript/" target="_blank" rel="noopener nofollow">https://typescript.tv/hands-on/upgrading-expo-in-a-react-native-project-with-typescript/</a>

I upgrade through
<a href="https://react-native-community.github.io/upgrade-helper/" target="_blank" rel="noopener nofollow">https://react-native-community.github.io/upgrade-helper/</a>
and will add TS to my project using this official docs page

I’m currently, upgrading my company’s project from RN 70 to 74
There are major changes, including Android files changing from Java to Kotlin
I’m unsure if other companies use Forked Git Repos as 3rd Party Libraries
Our uses quite few, and they cause hell of mess since those forked repos needs to be updated accordingly too.
No issues with iOS upgrade but having difficulty with Androids
We’ll get there :) Kudos to All RN Developers
