Infrastructure Management vm operator encounters an error when upgrading on OpenShift

When you are upgrading Infrastructure Management, you can encounter an error where the operator fails to install correctly.

Checking the OpenShift console InstalledOperators for project: management-infrastructure-management shows the operator in "Failed" state. Checking oc describe shows a message "conflicting CRD owner in namespace". For example,

oc describe operator ibm-management-infra-vm.management-infrastructure-management

This error CAN be seen when conflicting CSVs exist:

oc get csv -n management-infrastructure-management

Output:

Solution: Delete any older CSVs and this will allow the operator to install.

oc delete csv -n management-infrastructure-management ibm-management-infra-vm.v2.2.3-202011231109

oc delete csv -n management-infrastructure-management ibm-management-infra-vm.v2.2.3-202011230859
