Upgrading High-availability Deployments


Before you upgrade the JSA in a high-availability (HA) deployment, the primary host must be the active system in your deployment. The primary host must be upgraded before you manually upgrade the secondary host.

If the HA cluster is disconnected, or you want to add a new secondary HA host, you must reinstall JSA on the secondary HA. For more information about reinstalling software, see the Juniper Secure Analytics Installation Guide for your system. After you reinstall the secondary HA host, log in to the user interface to reconnect or to create a new HA cluster.

Before you upgrade a disconnected HA cluster, copy the following file from the primary to the secondary HA host to ensure that the management interfaces match between the two hosts after the upgrade finishes:

scp /opt/qradar/conf/capabilities/map_localhost_interfaces.txt.bak



Disk replication and failover are unavailable until the primary and secondary hosts synchronize and the needs upgrade or failed status is cleared from the secondary host.

After you upgrade the secondary host, you might need to restore the configuration of the secondary host. For more information about restoring a failed host, see the Administration Guide for your product.
