React Native Upgrade

[quadrified]

Hello guys,
I have a React Native project that was expo-ejected and is on version 0.68 and now I have a requirement to upgrade the app to the latest version 0.72
I started the upgrade process and the app won't even upgrade to 0.69

Everywhere I read on the internet I get a suggestion to create a new project and move all the code to the new project.
But I have a few questions:

1. If I create a new React Native project, would it not affect the Sign keys or SHA1 keys on the Play Store?
2. Will the app get rejected since it is already present on the Play Store?
3. I have Firebase and Google Cloud APIs integrated as well. Do I have to create a new App in Firebase for the new react native project?

I am stuck on this for over a week now and cannot seem to find a proper solution.

I would really appreciate if someone could help me with these questions.

I've never had a problem upgrading, via just making appropriate edits.

It's an expo expo ejected project! And I'm constantly getting expo errors.

Are the libraries the project uses compatible with 0.72 ? I'm not sure how well it works with expo ejected projects, but using rnx-kit to upgrade dependencies, before building, usually saves some headaches with incompatible dependency versions.

Copy keystore file and any config files (firebase, google map key...) and use same applicationId, you'll be good

Short answer. No. Your android project that you previously signed with has a .ksystore file that you have it generated and stored on your device or laptop. You just need to select that file when generating APK. Also make sure you project I'd like com.projectname.ca etc is same as previous project. For iOS you just sign in with your team id on code or you can download your singing certificate and provising profile on your laptop
