Failover Installation and Configuration

Installing and configuring failover includes the following:

Data migration is automatically performed when you set failover on an appliance. Data migration gets the standby appliance data in sync with the active appliance before setting up the failover relationship. This migration ensures that useful data on the active appliance is not accidentally overwritten during failover by data from the standby appliance.

For more information on how data migration works, see Data Migration Between Appliances. The procedures in that chapter are performed automatically during failover configuration.
