    Upgrading Junos Space Network Management Platform Overview

    To upgrade Junos Space Platform, you upload the Junos Space Platform image file to your existing fabric and perform the upgrade using the Junos Space Platform UI. When you perform an upgrade, all nodes in the Junos Space fabric are upgraded to the new software version.

    Caution: If you are upgrading to Junos Space Platform Release 16.1R1, follow the procedure outlined in Upgrading to Junos Space Network Management Platform Release 16.1R1.

    Note: For information about the features and updates for a specific Junos Space Platform release, refer to the Junos Space Network Management Platform Release Notes for that release.

    This topic has the following sections:

    Before You Begin

    Before you upgrade Junos Space Platform, ensure that you are aware of the following:

    • Upgrading Junos Space Platform clears existing user preferences (set using the User Settings global action icon in the Junos Space banner).
    • Back up all your Junos Space Platform data before you begin the upgrade process.
    • Download the Junos Space Platform Upgrade image from the Junos Space Network Management Platform Download Software page.

      Caution: Do not modify the filename of the software image that you download from the Juniper Networks support site; if you modify the filename, the upgrade fails.

    • You must log in as the default Super Administrator or System Administrator to upgrade Junos Space Platform.

    Pre-Upgrade Checks

    From Junos Space Platform Release 15.1R1 onward, the system checks for the following before you can upgrade the software:

    • Free disk space—If a node or a cluster fails to meet the minimum disk requirement, an error message is displayed. The minimum available disk space required is 10 GB in the / partition. The error message lists the IP address of the node that fails to meet the requirement. If you receive this error message, you cannot continue the upgrade.
    • MySQL replication and PostgreSQL replication—If the MySQL replication or PostgreSQL replication processes are turned off on any of the nodes, a warning message is displayed. Junos Space Platform checks the for Mysql, Mysql_Slave_IO, and Mysql_Slave_sql (MySQL) processes and postgres_sender, postgres_receiver, and postgresql (PgSQL) processes to obtain the status of the replication processes. The warning message lists the processes that are down. If you receive only this warning message, you can either continue or stop the upgrade.

    If both the preceding checks fail, an error message is displayed that lists all the preceding information. The upgrade process is not initiated.

    How an Upgrade Impacts Previously Installed Junos Space Applications

    Junos Space Platform provides the running environment for all Junos Space applications. Hence, the operations of the applications are interrupted during the upgrade. Only the applications that are supported on the version of Junos Space Platform to which you are upgrading are enabled. Other applications running on versions of Junos Space Platform prior to the version to which you are upgrading and that are not supported on that version might be disabled. You must upgrade these disabled applications to the respective compatible version.

    Note: Do not add disabled Junos Space applications using the Add Application page (Administration > Applications > Add Application).
