After a virtual failover client has been booted in live mode, its status is Invalid, it is no longer manged by the appliance, and virtual restores are no longer performed. For details, see Taking a virtual failover client live. If you no longer need the VFC to run in live mode, and you would like to create a new VFC for the client, you should first delete the existing VFC (see Deleting a virtual failover client) and then create a new one (see Setting up a virtual failover client).
