When migrating a suspended virtual machine, you also have the option of moving the associated disks from one datastore to another. The virtual machines are not required to be on shared storage.

Migration of suspended virtual machines is supported in ESX Server 3.x and ESX Server 3i and later only. Virtual machines created using ESX Server 2.x must be powered off before migration.

When you migrate a suspended virtual machine, the new host for the virtual machine must meet CPU compatibility requirements, because the virtual machine must resume executing instructions on the new host.

Migration of a suspended virtual machine consists of the following steps:


The configuration files, including the NVRAM file (BIOS settings), log files, and the suspend file 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.
