Usually you can easily upgrade an application from the Junos Space user interface. You must download the image file for the new version of the application, navigate to the Applications page (Network Management Platform > Administration > Applications) and select the application that you want to upgrade. From the right-click menu, choose Upgrade Application to upload the image file into Junos Space via HTTP or SCP.

But upgrade JunOS Space to latest version 16.1 is different and it is not a easy task. There are many steps to follow especially the last step to upgrade to 16.1 from 15.2R2. Here is my recent upgrade procedures.

Steps to upgrade JunOS Space 14.1  to the latest version 16.1:

1. From 14.1, first upgrade to 15.1

    Start Upgrading process from application page:

    You will be redirect to a new page to enter maintenance user name and password to start upgrade process. Username is maintenance. Password is the one you set up before or you can use this link https://kb.juniper.net/InfoCenter/index?page=content&id=KB16853 to reset it. 
    After waited 10 minutes, for somehow, the web gui lost connection. I have to manually restart httpd service to get back into maintenance window.
    Click the option Reboot JunOS Space:

    After reboot and waited 20 minutes, if Space is still in maintenance mode, you can run following commands to get system back into normal operation mode.

    Space release 15.1R4.1 (379522)

    2. Upgrade your Network Management Platform (NMP) to the latest release of your current version.
    For instance in my case means going from 15.1R1 to 15.1R4.
    3. Upgrade your other application
    After you have this done you need to upgrade all your Application modules to the latest version compatible for your NMP version (for example upgrade SD to 15.1R2). You didn’t mention having any application, but if you have please don’t skip this step, you can verify this in the NMP under Administration>Applications.

    Here is an example to upgrade Security Director from 14.1 to 15.1 R1.

    You had better to upgrade Security director to the highest release under that version before you go to next version of NMP. In this post, it has been upgrade to 15.1R2 before NMP upgraded to 15.2R1.

    4. Upgrade NMP to next Version’s first release
    in my case it is 15.2R1

    It is same steps as you upgrade from 14.1 to 15.1. It will take quite a while after rebooted to get system back into normal. You may have to those shell commands to start some services in step 1.

    Once 15.1 completed, you will have to upgrade to 15.1R2 version by uploading image file ‘15.2R2.4.img’.  Then you can do your applications such as security director, upgrade from 15.1R2 to 15.2R1 , 15.2R2.

    Here is the new look of Space Security Director 15.2 R1:

    5. Upgrade NMP from 15.2R2 to 16.1.
      Upgrade NMP from 15.2R2 to 16.1 is a little different from above steps. In Junos Space Network Management Platform Release 16.1R1, CentOS 6.8 is used as the underlying OS. As a direct upgrade of the OS from CentOS 5.9 to CentOS 6.8 is not supported, a direct upgrade to Junos Space Platform Release 16.1R1 by using the Junos Space Platform UI is also not supported. You must follow a multi-step procedure to upgrade to Junos Space Platform Release 16.1R1.

      Here is a link to show all steps. 

      Please pay special attention to the steps to upgrade to the latest version 16.1, there are different that other previous versions.
      Also, if you use a log collector. Versions 15.1, 15.2 and 16.1 of the log collector are not compatible and this will require to erase the old log collector and deploy the newer version instead.
      Finally, you can download the required files for the upgrade in this link:

      to change from one version to the other just use the drop-down menu om the right after selecting the specific application. Please let me know if you have any additional questions or concerns. 

      Troubleshooting
      Not Enough Disk Space
      You may get action failure when you do upgrade because of following error:

      “Upgrade Errors: 10.9.2.8: Has no enough disk space. Needs a minimum of 10G available space in “/” partition.

      Please click OK to stop the upgrade and fix the Upgrade Errors reported.”
