[edit on GitHub]

Steps to upgrade the Chef Automate HA are as shown below:

• Download the latest cli

   curl https://packages.chef.io/files/current/latest/chef-automate-cli/chef-automate_linux_amd64.zip | gunzip - > chef-automate && chmod +x chef-automate | cp -f chef-automate /usr/bin/chef-automate
  

• Download Airgapped Bundle, download latest Bundle with this:

  curl https://packages.chef.io/airgap_bundle/current/automate/latest.aib -o latest.aib
  

  Download specific version bundle with this, example version: 4.0.91:

  curl https://packages.chef.io/airgap_bundle/current/automate/4.0.91.aib -o automate-4.0.91.aib
  

• If we want to only upgrade FrontEnd Services i.e. Chef Automate and Chef Infra Server.

  chef-automate upgrade run --airgap-bundle latest.aib --upgrade-frontends
  

• If we want to only upgrade BackEnd Services i.e. Postgresql and OpenSearch.

  chef-automate upgrade run --airgap-bundle latest.aib --upgrade-backends
  

• To upgrade full Chef Automate HA System run this command from Bation Host:

  chef-automate upgrade run --airgap-bundle latest.aib
  

• To skip user confirmation prompt in upgrade, you can pass a flag

    chef-automate upgrade run --airgap-bundle latest.aib --auto-approve
    OR 
    chef-automate upgrade run --airgap-bundle latest.aib --upgrade-backends --auto-approve
    OR
    chef-automate upgrade run --airgap-bundle latest.aib --upgrade-frontends --auto-approve
  

Upgrade will also check for new version of bastion workspace, if new version is available, it will promt for a confirmation for workspace upgrade before upgrading the Frontend or backend nodes,

In case of yes, it will do workspace upgrade and no will skip this. We can also pass a flag in upgade command to avoid prompt for workspace upgrade.

 chef-automate upgrade run --airgap-bundle latest.aib --auto-approve --workspace-upgrade yes
    OR  
 chef-automate upgrade run --airgap-bundle latest.aib --auto-approve --workspace-upgrade no
