How can I use the current `*.keystore` to build successfully or migrate to new key but play store wi-CodePudding

I'm upgrading an android app to Target API level 30 (Android 11) because of it's required as of Nov 2021.

How can I use the current signing key *.keystore and build it without errors or migrate to new signing key but play store will also accept it?

If I use current *.keystore to sign my app, I got errors in Android Studio 4.2


Execution failed for task ':app:signReleaseBundle'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.FinalizeBundleTask$BundleToolRunnable
   > Failed to generate v1 signature

and

The security strength of SHA-1 digest algorithm is not sufficient for this key size

If I generate a new key by keytool , it works for building, but got errors on google play store after uploaded the aab.

errors from play store

Your Android App Bundle is signed with the wrong key. Ensure that your App 
Bundle is signed with the correct signing key and try again. Your app bundle is expected to be signed with the certificate with fingerprint:

$ keytool -list -v -keystore ./{yourkeystore}.keystore -alias xxxxxx -storepass xxxxxx -keypass xxxxxx

It shows Subject Public Key Algorithm: 2048-bit DSA key (3)
