For failover to a standby data center, the standby data center must meet the requirements before shifting the operations from the active data center to the standby data center. All the data created on the Experience Portal of the active data center must also be present on the standby data center before the failover. For example, data such as organizations, zones, and users. POM services must be in the Stopped state on all the POM servers of the standby data center before the failover.
