Syntax

Undo-VBRFailoverPlan -FailoverPlan <VBRFailoverPlan[]> [-Wait] [-WhatIf] [-Confirm] [<CommonParameters>]

Detailed Description

This cmdlet undoes the failover process. Undoing failover switches the workload back to source VMs. All changes that were made to the replicas during failover are discarded.

To switch back to the production VM and synchronize the changes made to the replica while failover, start a failback process. Run Start-VBRViReplicaFailback or Start-VBRHvReplicaFailback to fail back to the VMware or Hyper-V production VM. Note that failback is not a group process and must be performed for each VM individually.
