Before You Begin

Before you perform quick migration, check the following prerequisites and limitations.

  • 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 ESXi hosts.
  • The target datastore must have enough free space to store disks of the migrated VMs. 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.
  • The Delete source VM files upon successful migration option (see Finish Working with Wizard) applies if the following conditions are met:
  • VMs are powered on before migration.
  • VMware Tools are installed on VMs.
  • Veeam Backup & Replication uses its proprietary SmartSwitch technology to relocate VMs. For more information, see Quick Migration.


Veeam Backup & Replication does not keep encryption settings if a VM is migrated with VMware vMotion. After the migration process is finished, you will need to enable encryption for the migrated VM manually.

Integration with Instant VM Recovery

When you restore a VM using Instant VM Recovery, Veeam Backup & Replication starts the VM directly from a compressed and deduplicated backup file. To finalize recovery of a VM, you still need to move it to a new location. Moving the VM with VMware Storage vMotion or hot replication may require a lot of time and resources, or it may cause loss of valuable data.

Veeam Quick Migration was designed to complement Instant VM Recovery. Instead of pulling data from vPower NFS datastore, Quick Migration registers the VM on the target host, restores the VM contents from the backup file located in the backup repository and synchronizes the VM restored from backup with the running VM.

For more information, see Instant VM Recovery.

I want to report a typo

There is a misspelling right here:


I want to let the Veeam Documentation Team know about that.
