Undoing a Failover


You can undo a failover to discard changes from a virtual machine that runs on a secondary site and to return to using the original source VM on the primary site.

This operation is supported only for Hyper-V, Oracle Cloud Infrastructure, and VMware destination sites.

Before You Begin

For VMware destination sites: To perform failover, test boot, and failback operations for VMware destination sites, VMware tools must be installed on the source VMs before replicating the VMs.


  1. From the navigation pane, go to Disaster recovery > Replication Monitor.

    The Replication monitor page appears.

  2. For the replication pair that you want to undo a failover for, select the check box.

  3. In the upper-right area of the page, click the menu button , and then click Failback.

    The Undo failover dialog box appears.

  4. Click Undo failover.
