# isUpgraded

A Boolean value that indicates whether the customer upgraded to another subscription.

```
boolean isUpgraded
```

## Discussion

If `isUpgraded` is `true`, the customer has upgraded the subscription represented by this transaction to another subscription. This value appears in the transaction only when the value is `true`. To determine the service that the customer is entitled to, look for another transaction that has a subscription with a higher level of service. For more information about subscription groups and levels of service, see [Auto-renewable Subscriptions](https://developer.apple.com/app-store/subscriptions/).
