After using a test account to try out the Android for Work features, you might want to shift to the official enterprise account for proper management. Instead of creating a new account from the beginning, you can simply migrate to your enterprise account. Follow the steps given below to migrate your account.
An invitation email will be sent to the specified email ID, and the Admin must accept this invitation to begin the admin account migration process.
Navigate to MDM > App Repository > Sync Apps > Sync Playstore Apps. This will fetch the latest updated admin account.
Note: When Managed Google Play Admin account is migrated to a different user, the Managed Google Play terms of service need to be accepted again by the new user.
