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). To receive alerts about low space on the target datastore, configure global notification settings. For more information, see Specifying Other Notification Settings.
- 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.
