Backing up files for AOS upgrade

  • 1.  Backing up files for AOS upgrade

    Posted Sep 20, 2022 06:28 AM
    I am preparing for an upgrade from AOS 8.8x to 8.10.x. The setup consists of two Mobility Conductors (primary/standby), and a cluster of two md 72xx controllers
    The release notes recommends the files to backup. I have a few questions that I need advise on:
    1. Backing up flashes. The release notes recommends when using the WebUi to navigate the Mobility Conductor node hierarchy to backup the flash. As there aren't options to backup managed devices, this will only backup the flash for the Mobility Conductor and not the other nodes. Therefore, should I log directly into the the other nodes (standby mobility conductor and md's) to back them up? If I was to perform the backups via the cli should i run the backup from the # prompt, or from within mdconnect? 
    2. How can I backup the other recommended files on 8.10.x.? I know where to find the files on older 6.x releases.

      Configuration data

      WMS database

      Local user database

      Licensing database

      Custom captive portal pages

      x.509 certificates

      ​Kind regards

      In fact, almost all of the configuration to the MDs (Managed Device, controllers) are pushed from the MCR (Mobility Conductor), so having a backup of the MD may not be really required.
      You can just login to each of your MDs, create flashbackup and download the backup file.

      As far as I know, flashbackup is the only recommended backup as it includes the items you mentioned.

      8.8.x and 8.10.x are quite similar in this matter; so I would not expect too much troubles. Upgrade your MCR(s) first, the 8.10 MCR can still manage the MDs running 8.8. Then upgrade the MDs. Or are you planning an upgrade from 8.8 to 10.x? That is a different story...

      Hi Herman,
      Please apologise for my delay in responding to you. I thought I had replied via my phone.

      Thank you for the information. Support should update release notes with current, accurate information. The release note also references downloading SHA256, which I believe is no longer used, as digitally signed code is used. 

      Kind regards
