Perform the post-upgrade operation of expanding your vRealize Automation cluster to include a third appliance so that your environment remains aligned to this VMware Validated Design.

By adding a node to the vRealize Automation cluster and operating with the synchronous replication mode enabled, the embedded PostgreSQL database can automatically failover between nodes. Failover support improves resilience of the CMP stack to failures and reduces the number of manual failover procedures.
