Upgrading CloudBees Flow 5.x or Newer Versions

This section describes how to upgrade the software from CloudBees Flow 5. x or newer versions to 9.x . The procedure is the same as when you upgrade from CloudBees Flow 5. x or newer versions to 9.x and upgrade cluster configurations at the same time, except that you do not need to perform additional tasks to upgrade the cluster.

To upgrade from CloudBees Flow 5. x or newer versions to 9.x , use the ElectricFlow-<version> installer, which collects the CloudBees Flow service account credentials, uninstalls the current release, installs the latest CloudBees Flow release, configures the system with all property values mined, and restores custom files and data.

After preparing for the upgrade, make sure to shut down the CloudBees Flow server service before installing CloudBees Flow 9.x .
