Rolling back foundational services fails when upgrading from 1.10.3 to 1.10.4 by using the Red Hat OpenShift web console

When upgrading IBM Security QRadar® Suite Software from 1.10.3 to 1.10.4 by using the Red Hat® OpenShift® web console, foundational services is not rolled back to v3.19.x, which is the long-term service release (LTSR).

Procedure

Log in to your Red Hat OpenShift Container Platform cluster as a cluster administrator by typing one of the following commands, where <openshift_url> is the URL for your Red Hat OpenShift Container Platform environment.
- Using a username and password.
```
oc login <openshift_url> -u <cluster_admin_user> -p <cluster_admin_password>
```
- Using a token.
```
oc login --token=<token> --server=<openshift_url>
```
Set the $CP4S_NAMESPACE environment variable by typing the following command, where <cp4s_namespace> is the namespace where you are installing QRadar Suite Software.
```
export CP4S_NAMESPACE=<cp4s_namespace>
```
Set the $FS_NAMESPACE environment variable to your foundational services namespace by typing the following command.
```
export FS_NAMESPACE=$(oc get cm cp4s-config -o jsonpath="{.data.CSNamespace}" -n $CP4S_NAMESPACE)
```

Check the startingCSV version by typing the following command.

oc get sub ibm-cp-security-operator -o jsonpath="{.spec.startingCSV}" && echo

Remove the startingCSV field from the subscription by typing the following command.
```
oc edit sub ibm-cp-security-operator
```

Roll foundational services back to an earlier version and complete the upgrade by typing the following command.

oc exec deploy/cp-serviceability -- /opt/bin/cs_rollback --channel v1.10 $(oc whoami -t) ${CP4S_NAMESPACE} $FS_NAMESPACE -f

When the output of this command shows ibm-cp-security-operator updated, the upgrade is complete. The following example output shows that the upgrade is complete.

{"level":"info","ibm_datetime":"2022-09-27T12:17:20.509Z","caller":"misc/cleanup.go:332","message":"Deleted","Kind":"operator.ibm.com/v1alpha1, Kind=OperandBindInfo","Name":"ibm-licensing-bindinfo"}

{"level":"info","ibm_datetime":"2022-09-27T12:19:24.882Z","caller":"main/main.go:281","message":"ibm-cp-security-operator updated, waiting for install"}

Verify that foundational services is set to v3 by typing the following command.

oc get sub -n $FS_NAMESPACE ibm-common-service-operator -o jsonpath='{.spec.channel}{"\n"}'

Verify that foundational services is version 3.19.x, IBM NamespaceScope Operator is 1.13.3, and that QRadar Suite Software is 1.10.17 by typing the following command.
```
oc get csv | grep -E "foundations|ibm-cp-security|common-service|namespace"
```
