You can release an app update to production using a staged rollout, where you release an app update to a percentage of your users and increase the percentage over time.

New and existing users are eligible for to receive updates from staged rollouts. Staged rollouts can only be used for app updates, not when publishing an app for the first time.

When you increase the percentage of a staged rollout, your original group of users who are eligible to receive the APK is always included. If you upload a new APK to an existing staged rollout, your original group stays the same. When you create a brand new staged rollout, your staged rollout starts with a new user group.
