Delegate RealmConfiguration.MigrationCallbackDelegate
In order to handle manual migrations, you need to supply a migration callback to your
RealmConfiguration. It will be called with a Migration instance containing
the pre- and the post-migration Realm. You should make sure that the NewRealm
property on it contains a database that is up to date when returning. The oldSchemaVersion
parameter will tell you which SchemaVersion the user is migrating
from. They should always be migrating to the current SchemaVersion.
