Before you perform quick migration, check the following prerequisites:
- Backup infrastructure components that will take part in quick migration must be added to the backup infrastructure and properly configured. These include the source and target ESX(i) hosts.
- The target datastore must have enough free space to store disks of the migrated VM(s).
- If you want to use VMware vSphere vMotion to relocate VMs between hosts and/or VMware vSphere Storage vMotion to relocate VM disks between datastores, make sure that you have a VMware vSphere license covering these features.
- If you use tags to categorize virtual infrastructure objects, check limitations for VM tags. For more information, see VM Tags.
