Preparing CloudBees Jenkins Platform for migration to CloudBees CI

Before migrating your CloudBees Jenkins Platform client controller or operations center instance complete the following steps:

  1. Open an Assisted Update ticket with CloudBees Support to get a custom upgrade plan for your environment.

  2. Verify that your CloudBees Jenkins Platform operations center and controllers are on the latest release and your plugins are updated.

  3. Back up your $JENKINS_HOME directory from your CloudBees Jenkins Platform client controller or operations center instance.

If the BUILD_DIRECTORY is outside of the $JENKINS_HOME directory, then save a copy of this directory as well.
