You want to perform maintenance on an ESXi server and need to migrate its VMware VMs to another ESXi server. However, you do not need to migrate the VM datastore. You do not want to power off the VMs during the migration process.

Which of the following solutions should you choose?

  • vSphere vMotion
  • copying or cloning
  • cold migration
  • Storage vMotion
Explanation:

Of the available choices, you should choose VMware vMotion if you want to migrate a VMware virtual machine (VM) from one VMware ESXi server to another ESXi server without powering off the VM. In this scenario, you do not want to migrate the VMware datastore. VMware’s vSphere vMotion does not migrate datastores.
VMware’s ESXi server is a bare-metal server virtualization technology, which means that ESXi is installed directly on the hardware it is virtualizing instead of running on top of another operating system (OS). This layer of hardware abstraction enables tools like vMotion to migrate ESXi VMs from one host to another without powering off the VM, enabling the VM’s users to continue working without interruption.
You do not need to choose Storage vMotion to perform the migration in this scenario, because Storage vMotion allows migration of both the VM and its datastore. The datastore is the repository of VM-related files, such as logs and virtual disks. When migrating a VM by using Storage vMotion, both the virtualized environment and the datastore can be moved to a new host without powering down or suspending the VM.
You should not choose cold migration, copying, or cloning in this scenario. Cold migration is the process of powering down a VM and moving the VM or the VM and its datastore to a new location. While a cold migration is in progress, no users can perform tasks inside the VM. Both copying and cloning create new instances of a given VM. Therefore, neither action is a form of migrating a VM to another host. Typically, a VM must be powered off or suspended in order to successfully copy or clone it
