Hello @Mahavir Saroj Thank you for reaching out to us on Microsoft Q&A platform. Happy to answer any questions you may have!

When you initiate the final migration in Azure Migrate, the virtual machine is created in Azure using the replica managed disks that were created during the replication process. Here is a high-level overview of the backend process:

1. Azure Migrate performs a final synchronization of the source virtual machine to ensure that all changes are replicated to the replica managed disks.
2. The source virtual machine is shut down to ensure zero data loss during migration.
3. The replica managed disks are used to create the virtual machine in Azure.
4. The virtual machine is started in Azure and the IP address is assigned.
5. The virtual machine is added to the target virtual network and subnet.

During the final migration process, Azure Migrate also performs a number of post-migration tasks, such as updating DNS records and configuring load balancers, if applicable.

It is important to note that the final migration process can take some time to complete, depending on the size of the virtual machine and the amount of data that needs to be migrated. You should also ensure that you have tested the migration thoroughly before initiating the final migration to minimize downtime and ensure a successful migration.
