Upgrading Unravel from version 4.7.x.x to 4.7.x.x
  1. Navigate to the ansible-installation directory and create a copy of the vars_template.yml file.

    cp vars_template.yml vars.yml
  2. Edit vars.yml by using any editor. For example, the vi editor.

    vi vars.yml
  3. In the vars.yml file, update values for the following parameters:




    • Y: If you set this variable to Y, it skips the step to download and extract the Unravel tarball and configures or sets up Unravel.

    • N: If you set this variable to N, it downloads and extracts the Unravel installation tarball.


    Specify the URL of the Unravel distribution.


    Specify the username of the Linux user who owns Unravel.


    Specify the names of the user groups to which the Linux user belongs.


    Specify the path where Unravel is installed.


    Specify the Unravel version to which you want to upgrade.


    Specify whether you want to skip the upgrade.


    Specify if you want to configure a separate data directory outside the Unravel directory.

  4. In cloud_node, specify the hosts file (if the Unravel upgrade is for a cloud platform).

  5. In core_node and edge_node, set the corresponding hosts file (if the Unravel upgrade is for an on-premise platform).

  6. From the Unravel server, run the Ansible playbook.

    ansible-playbook -i inventories/ upgrade_unravel.yml -e @vars.yml -vvv

    Unravel is upgraded to the specified version.
