Migrate OData Applications to REST API

Migrate messaging-based (sometimes called iMO-based) OData applications to REST API-based, to take advantage of REST services capabilities. This enables you to run mobile applications on-premise and in the cloud.

Prerequisites
  • Import the new REST client libraries from the OData SDK into your Android or iOS development environment.
  • Arrange access to a test environment for both on-premise and cloud testing.
Task
  1. In your development environment, modify the messaging-based (sometimes called iMO) application logic to use REST-based services.
    Some areas you may need to address:
    • Registration
    • Settings exchange
    • Request response
    • End-to-end tracing
    • Native push notifications
    • For the cloud, the application may support CAPTCHA if required.
    For supporting information:
    • For information related to migrating OData applications to REST API, see Guidelines for On Premise and Cloud Applications.
    • For API information for all of the above, which are different for the REST SDK, see Developer Guide: OData SDK:
      • Development Task Flow Using REST SDK (HTTP Channel) – iOS section
      • Development Task Flow Using REST SDK (HTTP Channel) – Android section
    • For new API information, see OData SDK API Changes in Version 2.3.
  2. Recompile the application.
  3. Test the application in a device simulator or emulator, and in the test environment (both on-premise and cloud configurations). Make modifications as needed.

  4. Deploy the application to the production environment.
