How Does Virtual Machine and Storage Migration Work?

Storage Migration technology enables you to move a virtual machine and its storage to another location without downtime.

• During migration the virtual machine hard drive is copied from one location to another

• Changes are written to both source and destination drives

• You can move virtual machine storage to same host, another host, or server message block share

• Storage and virtual machine configuration can be in different locations

How Live Migration WorksThe Live Migration process consists of four steps:1. Migration setup2. Guest-memory transfer3. State transfer4. Clean up
