Before you perform failback, check the following prerequisites:
- VMs for which you plan to perform failback must be successfully replicated at least once.
- VM replicas must be in the Failover state.
- On non-Microsoft Windows SMB3 storages, for example, Tintri, Veeam Backup & Replication may display the "Failed to disable integrity bit on disk N" warning during VM restore. You can ignore this warning for non-Microsoft Windows SMB3 storages.
- You must check the platform compatibility matrix. For more information, see Supported Platforms for Replica Failback.
