Handling data migration with DataStore
If you have built Android applications before, you might have used SharedPreferences; the good news now is that there is support for migration, and you can migrate from SharedPreferences to DataStore using SharedPreferenceMigration. As with any data, we will always modify our dataset; for instance, we might want to rename our data model values or even change their type.
In such a scenario, we will need a DataStore to DataStore migration; that is what we will be working on in this recipe. The process is pretty similar to the migration from SharedPreferences; as a matter of fact, SharedPreferencesMigration is an implementation of the DataMigration interface class.
Getting ready
Since we just created a new PreferenceDataStore, we will not need to migrate it, but we can look at ways to implement a migration in case a need arises.
