You can use the CloudBees CI Helm chart to migrate an existing CloudBees CI installation to Helm.
Installations of CloudBees CI performed without Helm used a YAML file, and administrators had to directly modify the
cloudbees-core.yaml file to update or modify the CloudBees CI configuration.
Switching to Helm to manage CloudBees CI gives administrators the ability to "offload" administration of CloudBees CI to Helm and automate the upgrade process.
Additionally, Helm 3 is a pure client-side solution (unlike Helm 2, which required a server-side component with full admin access), so there are no limitations to using it instead of the older YAML manifests.
As all migrations carry a risk of data loss, CloudBees strongly recommends backing up your operations center and
JENKINS_HOMEprior to migrating. For more information, see the Backup and restore guide.
Add the CloudBees Helm chart repository to your Helm environment. For more information, see How to install CloudBees CI on modern platforms using Helm
If you wish to use a custom values file to set options, set that file up prior to starting the migration.
