To perform a data sync with the peer appliance before failing over, set this to true. All users on the existing primary appliance will be disconnected during the data sync, and no other operations will be available until the swap is complete.

To fail over without a final data sync, set this to false or omit this field.

This option is only applicable when contacting the primary appliance and attempting to set its role to "backup".

If this is set to true, then this appliance will become the backup even if the peer appliance cannot be contacted.
