The correct term for the movement of virtual machine instances is virtual machine migration.

Explanation:

Virtual machine migration refers to the process of moving a running virtual machine (VM) from one physical host to another without disconnecting the client or shutting down the VM. This is critical in cloud computing environments and for maintaining high availability, load balancing, and system maintenance.

Migration can be done in two main forms:

1. Live Migration - This allows the VM to continue running during the migration process, minimizing downtime.
2. Cold Migration - This requires the VM to be powered down before it can be moved to a new host.

Choosing virtual machine migration helps enhance resource utilization and improves performance, leading to better overall efficiency in data center operations.
