To fallback to a previously active data center, the data center must meet requirements prior to shifting the operations.
The Experience Portal of the Data Center-1 must contain all the data that was present on the Experience Portal of the active Data Center-2. For example, the organizations, zones, and users created on Experience Portal of active data center must also be present on the Experience Portal of the standby data center prior to fallback.
POM services must be in Stopped state on all the POM servers of the Fallback Data Center-1 prior to fallback.
