Preparing for software upgrade

Use this procedure to prepare for the software upgrade from the old release to the new release.
  1. Display system information and status.
    Log in to the deployer VM using SSH.
    1. Verify that the Helm charts are running the current release. 
      [root@fss-deployer ~]# export KUBECONFIG=/var/lib/fss/config.fss
[root@fss-deployer ~]# helm list

    2. Verify that the pods are all up and running. 
      [root@fss-deployer ~]# kubectl get pods

  2. Back up the necessary files from the deployer VM.
    Copy the following files to a directory that is outside of the deployer VM:

    • SSH files

      /root/.ssh/id_rsa

      /root/.ssh/id_rsa.pub

      /root/.ssh/known_hosts

    • Input JSON configuration file that was used to install the Fabric Services System, for example:

      /root/customer-input.json

    • The HTTPS related certificate files that were used to install Fabric Services System, for instance:

      /root/tls.crt

      /root/tls.key

    • Optional files

      SRL image tar files that were added to the old deployer VM

  3. Back up the Fabric Services System.

    For instructions, see Backup and restore in the Fabric Services System User Guide.

  4. Shut down the old deployer VM.
    Note: Ensure that the old deployer VM is not configured to automatically restart.
  5. Create a new deployer VM using the image for the new release.
    For instructions, see Fabric Services System deployer VM creation. The new deployer should have the same network configuration and the same IP address of old deployer VM.
  6. Copy the files that you saved in Step 2 to the new deployer VM in the same locations.
