Upgrading the IBM Process Mining application

Prerequisites

Upgrading the dependencies

You can upgrade the IBM Process Mining application from version 2.1.1 to version 2.2.0. The following instructions are applicable to both CP4BA and non-CP4BA environments. Do the following steps to update the namespace for IBM Process Mining:

Set the PM_PROJECT variable to your namespace with the following command:
```
export PM_PROJECT=<'YOUR-NAMESPACE'>
```
Verify the current IBM Process Mining version with the following command:
```
oc get csv -n $PM_PROJECT | grep processmining
```

Delete the catalog source with the following command:

oc delete catalogsource ibm-automation-processminings -n $PM_PROJECT

Upgrade the IBM Process Mining Operator catalog with the following command:

cat <<EOF | oc apply -f -
apiVersion: operators.coreos.com/v1alpha1
kind: CatalogSource
metadata:
  name: ibm-automation-processminings
  namespace: ${PM_PROJECT}
spec:
  displayName: ibm-process-mining-4.2.0
  publisher: IBM
  sourceType: grpc
  image: icr.io/cpopen/processmining-operator-catalog@sha256:cc2d6286fce49a84f9d9c24170d9a267158a91bfd104c8173de2f9efc8d94076
  updateStrategy:
    registryPoll:
      interval: 45m
EOF

Verify that the catalog source is ready with the following command:
```
oc get catalogsource ibm-automation-processminings -n ${PM_PROJECT} -o jsonpath='{.status.connectionState.lastObservedState}'
```
Wait until the output is READY before proceeding to the next step.

Create the subscription with the following command:

cat <<EOF | oc apply -f -
apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
  name: processmining-subscription
  namespace: processmining
spec:
  channel: v4.0
  installPlanApproval: Automatic
  name: ibm-automation-processmining
  source: ibm-automation-processminings
  sourceNamespace: processmining
EOF

Check the status of the processmining operator with the following command:
```
oc get csv -n $PM_PROJECT | grep processmining
```
You should see the following message:
```
ibm-automation-processmining.v4.2.0          
IBM Process Mining 4.2.0        
ibm-automation-processmining.<previous_operator>
Succeeded
```
You can now verify if Redis upgrade was successful. For more information, see Upgrading the dependencies.
