So you want to know if once updated, the old version of the App can still be used on Play Store? Or are you asking how to update an App?G0dsquad– G0dsquad2018-06-14 09:48:53 +00:00Commented Jun 14, 2018 at 9:48

Then I don't think it's possible to migrate unless it's stored in a Cloud service or SQLite. stackoverflow.com/questions/44376002/…G0dsquad– G0dsquad2018-06-14 10:27:49 +00:00Commented Jun 14, 2018 at 10:27

As long as the application:
- is built to an APK or App Bundle
- has the same package name / application id
- has the same signing certificate
then Google Play doesn't care what language your app was built with, you can just replace one APK with another.
As with any update, internal data is stored on app specific local storage. You will have to write code in the new React app to read saved code from the Java app. How hard this is depends on how you wrote the internal saved data.
