Upgrading Primary and Secondary Clusters through CLI

Primary and secondary clusters can be upgraded for datacenter redundancy through CLI Command-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions. option 4 System Configuration commands. Under option 4, you must use option 8 for Data.

To perform any upgrade for the secondary cluster, you must use the CLI option. You cannot update the secondary cluster through the user interface.
