After you perform failback, you might have to reconfigure the vRealize Suite components to restore the original configuration of the protected and recovery sites.
For vRealize Automation, you do not have to reconfigure any components after failback. If for any reason, the failback fails, see related information under Configure Load Balancer.
For vRealize Operations Manager, if your disaster recovery plan requires you to change IP addresses after restoring the clusters on a remote host, see Change the IP Address of Nodes After Restoring a Cluster on a Remote Host. You would have to reconnect the remote collector node, if you have protected it by using Site Recovery Manager. For more information on how to reconnect the remote collector node, see Reconnect Remote Collector Node
For vRealize Orchestrator and vRealize Log Insight, you do not have to reconfigure any components after the failback.
