Hello @Gundavarapu Srinivasarao - Welcome to Microsoft Q&A community forum!
From the details provided above I can infer that you were able to successfully perform test failover. Now that, you want the changes you made to be replicated to primary VM (on-premise). To do so, you need to perform failback operation and as part of failback - reverse replication. The details are documented here - https://learn.microsoft.com/en-us/azure/site-recovery/hyper-v-azure-failback#fail-back-to-the-original-location
Hope this clarifies!
