Precautions for Upgrading Appliances
Follow certain precautions before upgrading JSA appliances.
Ensure that you take the following precautions:
Back up your data, and confirm that backups are complete before you begin the upgrade.
For more information about backup and recovery, see the Juniper Secure Analytics Administration Guide for your product.
Ensure that you either have a JSA Console connected to your hardware or have a remote connection to the management port (often called an out of band management setup). This is important because, if you encounter a problem while you are reinstalling RHEL, you will need to access the server through one of these connections.
Upgrade all managed hosts before you deploy changes.
Close all open JSA sessions to avoid excess errors in your log file.
