Cold migration is the migration of a powered-off virtual machine. With cold migration, you have the option of moving the associated disks from one datastore to another. The virtual machines are not required to be on shared storage.

The virtual machine you want to migrate must be powered off prior to beginning the cold migration process.

CPU compatibility checks do not apply when you migrate a virtual machine with cold migration.

A cold migration consists of the following tasks:


The configuration files, including the NVRAM file (BIOS settings), and log files, as well as the disks of the virtual machine, are moved from the source host to the destination host’s associated storage area.


The virtual machine is registered with the new host.


After the migration is completed, the old version of the virtual machine is deleted from the source host.
