Before any planned switchover from a primary to a Disaster Recovery (DR) site, you must verify that the health status of the applications replicating data from the primary to the DR site is completely operational.
The following Avaya Oceana® core applications replicate data from the primary site to the DR site:
Unified Collaboration Administration (UCA)
System Manager and Avaya Breeze® platform replication
Avaya Context Store Snap-in (CS)
Omnichannel database using CACHE mirroring
The following surrounding applications in Avaya Oceana® replicate data from the primary to the DR site:
Avaya Aura® System Manager primary to System Manager Geo in the DR location
Avaya Control Manager database replication from primary to DR location
Avaya Aura® Communication Manager from primary to DR ESS
Important:
Validate the replicating function of all these replicating applications before a partial DR switchover. If you do not validate, it leads to issues during the switchback process.
