Cleaning up foundational services version 3.x control namespace after upgrading to version 4.x

After you uninstall IBM Cloud Pak foundational services from version 3.x to 4.x, some components of the foundational services remain in the control namespace. To uninstall these components, you can download the following script from the scripts-adopter branch of the ibm-common-service-operator GitHub repository: cleanup_cp2_control.sh

Parameters:

 --oc string                                    File path to oc CLI. Default uses oc in your PATH
