Which migration type is performed when moving an OS from a physical server to a virtual environment?

The migration type performed when moving an operating system from a physical server to a virtual environment is known as P2V, which stands for Physical to Virtual. This process involves converting a physical machine, including its operating system, applications, and data, into a virtual machine that can run on a hypervisor within a virtualized environment.

P2V migrations are essential for organizations looking to reduce hardware costs, improve scalability, or implement disaster recovery strategies. By virtualizing physical servers, resources can be allocated more dynamically, and maintenance becomes easier since virtual machines can be moved or cloned with greater flexibility.

Other migration methods do not apply in this context. For instance, vMotion refers specifically to the live migration of virtual machines (VMs) between hosts without downtime and does not involve physical servers. The term "private to public" typically refers to the migration of resources between a private cloud and a public cloud and is not focused on the physical to virtual transition. Lastly, V2V, or Virtual to Virtual migration, is concerned with moving virtual machines from one virtual environment to another, which does not relate to the original presence of a physical server.
