You can uninstall individual components, all components, or completely remove Edge from your
system. In addition, you can [roll back Edge](https://docs.apigee.com/private-cloud/v4.52.01/rollback-45000) if you upgraded.

## Uninstall individual components

To uninstall a component, use the `apigee-service` utility in the form:

```
/opt/apigee/apigee-service/bin/apigee-service component_name uninstall
```

Where <var translate="no">component_name</var> identifies the component you want to uninstall. The possible
values of <var translate="no">component_name</var> include the following:

- `apigee-cassandra` (Cassandra)
- `apigee-openldap` (OpenLDAP)
- `apigee-postgresql` (PostgreSQL database)
- `apigee-qpidd` (Qpidd)
- `apigee-sso` (Edge SSO)
- `apigee-zookeeper` (ZooKeeper)
- `edge-management-server` (Management Server)
- `edge-management-ui` (new Edge UI)
- `edge-message-processor` (Message Processor)
- `edge-postgres-server` (Postgres Server)
- `edge-qpid-server` (Qpid Server)
- `edge-router` (Edge Router)
- `edge-ui` (Classic UI)

In addition to these components, you can also uninstall the `apigee-provision` and
`apigee-validate` components.

For example, to uninstall the Edge UI:

```
/opt/apigee/apigee-service/bin/apigee-service edge-ui uninstall
```

This command does not delete any data or log files. It only deletes the component.

## Uninstall all components

To uninstall all Apigee components on the node, uninstall the `apigee-service`
utility:

```
/opt/apigee/apigee-service/bin/apigee-service apigee-service uninstall
```

This command does not delete any data or log files. It only deletes the components.

## Remove Edge

To completely remove Edge from your system:

1. Stop all Edge services running on the machine:

   ```
   /opt/apigee/apigee-service/bin/apigee-all stop
   ```
2. Clear the yum cache:

   ```
   sudo yum clean all
   ```
3. Remove all the Apigee RPMs:

   ```
   sudo rpm -e $(rpm -qa | egrep "(apigee-|edge-)")
   ```
4. Remove the installation root directory:

   ```
   sudo rm -rf /opt/apigee
   ```
5. Remove the Nginx directory:

   ```
   sudo rm -rf /opt/nginx
   ```
