    Managing J Series and SRX Series Device Software Versions Overview

    You can use Network and Security Manager (NSM) to upgrade or adjust the software on managed J Series and SRX Series devices running JUNOS Release 9.3 or later.

    When a software upgrade is applied to a J Series or SRX Series device with dual Routing Engines, the upgraded software is applied to both Routing Engines. The backup is upgraded first. The router then reboots and the backup becomes the master. Then the former master is upgraded, as is the standard procedure for upgrading J Series and SRX Series devices with dual Routing Engines.

    For steps on updating the device software version, see “Upgrading the Device Software” in the Network and Security Manager Administration Guide.
