Rolling Back the Upgrade Within 14.1.2

13.1.2 Rolling Back the Upgrade Within 14.1.2

If the Oracle Unified Directory (OUD) upgrade fails, you can rollback to the previous OUD 14c container image, fix the issue, and then retry the upgrade.

You can also rollback if the upgrade was successful but you subsequently have functional issues.

To rollback the Oracle Unified Directory (OUD) installation perform the following steps:

Rollback the OUD deployment using the following command:
```
helm rollback <release_name> -n <namespace>
```
For example:
```
 helm rollback oud-ds-rs -n oudns
```
The output will look similar to the following:
```
Rollback was a success! Happy Helming!
```
The helm rollback will perform a rolling restart of the OUD pods.
Run the following command and make sure all the OUD pods are started:
```
kubectl get pods -n <namespace> -w
```
Note:
The -w flag allows you watch the status of the pods as they change.
For example:
```
kubectl get pods -n oudns -w
```
You can also tail the logs for the pods by running:
```
kubectl logs -f <pod> -n oudns
```

Once the pods are up and running, you can run the following command to show the previous OUD 14c container image is used by the pods:

kubectl describe pod <pod> -n <namespace> | grep image

For example:

kubectl describe pod oud-ds-rs-0 -n oudns | grep image

The output will look similar to the following:
