## Upgrading Calico on OpenShift 4

Make a manifests directory.

```bash
mkdir manifests
```

{% include content/install-openshift-manifests.md install_type="upgrade" %}

Apply the updated manifests.

```bash
oc apply -f manifests/
```

You can now monitor the upgrade progress with the following command:

```bash
watch oc get tigerastatus
```

If you were upgrading from a version of Calico prior to v3.14 and followed the pre-upgrade steps for host endpoints above, review traffic logs from the temporary policy,
add any global network policies needed to whitelist traffic, and delete the temporary network policy **allow-all-upgrade**.
