Official documentation says that

In general, the recommended strategy for all developers is to sign all of your applications with the same certificate, throughout the expected lifespan of your applications.

You should check this documentation.

In your case if you create new keystore for your existing app on google play. Google play console will prompt error that same package exist already. So you must get your old Keystore for further updates of your application.

For your case check this.

If you are having old keystore then you should go with that one instead of creating new one.

  • No, it's not possible to create new keystore. System does not matter you should keep a copy of the keystore as a backup. If you are not having any copy then it's not possible to reproduce keystore file. According to android standards every application is signed with unique keystore file and that keystore file is required throughout life cycle of that application. If keystore is deleted by mistake then you should try system recovery. – Ahsanwarsi Apr 21 '16 at 06:24
