What does physical-to-virtual migration involve?

Physical-to-virtual migration specifically refers to the process of transferring an operating system, applications, and data from a physical server to a virtual server. This method allows organizations to utilize virtualization technologies, thereby increasing efficiency, reducing costs, and optimizing resource utilization. By converting physical systems into virtual machines, businesses can take advantage of the benefits of virtualization, such as flexibility, scalability, easier backup and recovery, and improved disaster recovery solutions.

The other options do not accurately describe this process. Creating backups of physical data pertains more to data protection rather than migration. Upgrading physical hardware focuses on improving existing physical components rather than transferring to a virtual environment. Deploying additional physical servers is about expanding physical infrastructure, which is opposite to the goal of migrating to a virtual setting. Thus, the correct choice emphasizes the essence of moving a physical system into a virtual context, highlighting the strategic shift towards virtualization in IT environments.
