Completing the IBM Automation Workstream Services upgrade

After the operator upgrades your deployment of IBM Automation Workstream Services, you might need to perform some additional steps to complete the upgrade process.

Procedure

Optional: If you want Workstream Services to continue to be federated, upgrade Process Federation Server. For more information, see Upgrading Process Federation Server on Red Hat® OpenShift® from 24.0.0.
Optional: If you enabled full text search or you federated Workflow with Process Federation Server, you must rebuild the case indexes. The process indexes are automatically rebuild in the new OpenSearch cluster.
For more details on case indexing REST API, see Indexing case instances.
Note: Ignore this step if you are using external Elasticsearch or OpenSearch and did not migrate to the OpenSearch that is included with Cloud Pak for Business Automation.
To validate the upgrade:
1. You can see which images were recently pulled by running a command similar to the following command, where ${NAMESPACE} is your Cloud Pak for Business Automation namespace:
```
for i in $(oc get pod -n ${NAMESPACE} --no-headers|awk '{print $1}') 
do 
  oc describe pod $i| awk '/Pulled/{print "'$i'",$0}'
done
```
2. To check the status of the pods, run the following command:
```
oc get pods -n ${NAMESPACE}
```
3. Get the URLs and log in to Workstream Services to get started.
  To get the URL of the web applications and the user credentials to log in, access the Config Maps from the OpenShift web console.
  - Log in to your cluster web console.
  - Select your namespace.
  - In the left window, select Workloads > Config Maps.
  - Find cp4ba-access-info. You can get IBM Cloud Pak® dashboard information from workflow-server-access-info.
  - Access Workstream Services by using the URLs in workflow-server-access-info.
You can check the status and endpoints for Workstream Services either from the Red Hat OpenShift console or from the command line.
- To check the status and endpoints from the OpenShift console, complete the following steps:
  1. In the left menu, select Operators > Installed Operators.
  2. Select your project (namespace) from the window on the right.
  3. Click the installed operator for IBM Cloud Pak for Business Automation.
  4. Go to the CP4BA deployment tab and select your deployment (for example, icp4adeploy).
  5. Go to the YAML tab and check the status of every component under the status: element. For example:
```
 status:
          components:
                  ...
                 baw:
                   bawDeployment: Ready
                   bawService: Ready
                   bawZenIntegration: Ready
                 baml:
                   bamlDeployment: Ready
                   bamlService: Ready
                   ...
```
  6. For endpoint details, search for endpoints under the status: element. For example:
```
endpoints:
         ...
         - name: BAW Login URL
           scope: External
           type: UI
           uri: 'https://baw-bawins1.apps.bawdev.mydomain.com/ProcessPortal'
           ...
```
  7. You can also find the endpoints in the Details page.
- To check the status and endpoints from the command line, complete the following steps:
  1. Get your deployment name by running the following command:
```
oc get ICP4ACluster -n <your_project>
```
  2. To get the deployment YAML and check the status and endpoints, run the following command:
```
oc get ICP4ACluster icp4adeploy -o yaml
```
