When we were planning for our underneath OS migration from AIX 7.1 TL05 SP02 to AIX 7.2 TL02SP03 we moved the active database to another node. After failover, we rebooted the primary node and successfully upgraded the OS on the node. Once we perform the basic health check then we will fall back on the primary node in scheduled maintenance.
