This topic explains the process for upgrading Cisco IoT FND in high-availability (HA) configuration or clustered mode, outlining the key steps required to ensure a successful upgrade.
Upgrading IoT FND in HA configuration or clustered mode involves a series of coordinated steps to ensure system integrity and minimal downtime.
-
Upgrade the Oracle database as the initial step.
-
Stop all application servers that are part of the cluster before proceeding.
-
Upgrade all FND applications to the latest version.
-
Run db-migrate post upgrade on one of the application servers.
-
Start FND services one by one to complete the upgrade process.
For more information about upgrading the Oracle database, refer to the related documentation.
For instance, after stopping all application servers in the cluster, upgrade the Oracle database, then proceed to upgrade each FND application, run db-migrate on one server, and finally start the FND services sequentially.
