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.
- Veeam Backup & Replication ignores the cardinality setting for VM tag categories. For example, you create a tag category Priority and set cardinality to One tag per object. In the tag category, you create two tags: Normal and High. You assign the Normal tag to a VM folder and the High tag to a VM in this folder. If you now select to migrate objects with the Normal tag, the VM with the High tag will also be migrated (since Veeam Backup & Replication regards that VMs and templates in the VM container inherit the tag assigned to the container).
