Hi Richika,
For me, this is a change of a service that might be managed as an order. Ideally, it should start with a product order (TMF622) which would derive in a service order (TMF641). I guess that you could use other approaches to manage this, for instance, using the Service Activation and Configuration API directly (TMF640), buy it would depend on your solution and architecture.
Hope it helps.
