# Migrating from 1.0

#### Migrating from com.batch.cordova 1.x

Batch's cordova plugin 2.0.0 update being a major version, it brings some breaking change to existing implementations:

* batch.push.setGCMSenderId() has been *removed*. Android now uses FCM, which requires you to add a `google-services.json` file to your project. [More info here](/developer/sdk/cordova/sdk-integration.md#android-setup).
* "setCanUseAndroidID" has been *removed* from the config object. You can safely leave the key, but it will be ignored.

For any other supported API use cases, your code requires no change.

#### Migrating from batch.userProfile

If you've previously used `batch.userProfile`, you can easily use Batch User. You will still be able to set a custom region, language or identifier with the new API.

The main difference between Batch User and `BatchUserProfile` is that you'll now be required to use an editor object in order to make changes, and then save them. This transactional behaviour brings additional thread-safety and better performance.

That way, what used to be:

```javascript
// Use the user profile to set custom language and data 
batch.userProfile.setLanguage("en"); // Language must be 2 chars, lowercase, ISO 639 formatted
batch.userProfile.setRegion("US"); // Region must be 2 chars, uppercase, ISO 3166 formatted
batch.userProfile.setCustomID("john.doe");
```

will become this:

```java
batch.user.getEditor()
    .setLanguage("en") // Language must be 2 chars, lowercase, ISO 639 formatted
    .setRegion("US") // Region must be 2 chars, uppercase, ISO 3166 formatted
    .setIdentifier("john.doe")
    .save(); // Don't forget to save the changes!
```

{% hint style="info" %}
`batch.userProfile` is now deprecated, but will continue to work. We still suggest you migrate in the near future, so you can take advantage of the new capabilities.
{% endhint %}
