Techopedia Explains Cold Migration

The terms cold and hot migration are often applied to the migration of virtual machines in a virtualized system. With cold migration, the use of data stores is more flexible. Like any kind of less engaged migration, cold migration for virtual machines may allow for more effective transfer with less complexity. However, it may require downtime as the system needs to be powered down.
