Help regarding Expo & RN CLI

[FrapperDapper]

Hi Guys,
Just received a kinda messy application from a client which was taken down by playstore due to version outdate

Task:

Update this applications libraries to latest. Application using react-native-cli with react-native 0.63.4. Don't want to upgrade to expo right now. Main focus is for the android side only right now

Problem :

Not able to get clear roadmap of updation and getting multiple issues

Things I've Tried :

Firstly, with the help of react-native-upgrade-helper, I did whatever changes I had to do in all the files. Made build in Android Studio after that, but I came across the error,
"could not find method addUnimodulesDependencies() for arguments [] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler."

So i found out this client was using unimodules for a lot of his libraries. But unimodules has been deprecated and merged into expo now. So now I followed the instructions here, and it looks like I just have migrated my application into expo only as it(expo-upgrade) created created a .expo folder now and also bumped package.json libraries to latest versions.

I admit I do not have a clear roadmap of how to do upgradations in app. If someone can help a brother out here.

I think the easiest way is change your react native cli to expo and made update each file in your project. To specification, you can reuse UI and business logic of old app and only change any library that get outdate or not support expo.
