You can check the RPM versions you currently have installed, to see if they
need to be updated, by entering:

```
apigee-all version
```

To update your installation, perform the following procedure on the Edge nodes:

1. On all Edge nodes:

   1. Clean the Yum repos:

      ```
      sudo yum clean all
      ```
   2. Download the latest Edge 4.50.00 `bootstrap_4.50.00.sh` file to `/tmp/bootstrap_4.50.00.sh`:

      ```
      curl https://software.apigee.com/bootstrap_4.50.00.sh -o /tmp/bootstrap_4.50.00.sh
      ```
   3. Install the Edge 4.50.00 `apigee-service` utility and dependencies:

      ```
      sudo bash /tmp/bootstrap_4.50.00.sh apigeeuser=uName apigeepassword=pWord
      ```

      where <var translate="no">uName:pWord</var> are the username and password you received from Apigee.
      If you omit <var translate="no">pWord</var>, you will be prompted to enter it.
   4. Update the `apigee-setup` utility:

      ```
      sudo /opt/apigee/apigee-service/bin/apigee-service apigee-setup update
      ```
   5. Use the `source` command to execute the `apigee-service.sh` script:

      ```
      source /etc/profile.d/apigee-service.sh
      ```
2. On all Edge nodes, execute the `update.sh` script for the `edge` process:
