For disaster recovery, follow these best practices.
Use Site Recovery Manager (SRM) for disaster recovery.
VMware Site Recovery Manager is the only supported tool for disaster recovery.
See Disaster Recovery by Using Site Recovery Manager at vRealize Suite Documentation.
Migrate or recover vRealize Operations virtual machines to an identical network configuration
The recovery site must consist of an identical network configuration, if possible, to minimize transition changes when the recovery site becomes active.
Change the IPs of the nodes when the recovery site does not have an identical network configuration
Regularly test recovery plans and always clean up the executed recovery tests
To ensure a reliable recovery, test frequently to ensure latest updates are applied to the recovery site and clean up when tests have been completed.
