# Upgrade the appliance hardware | RS On-prem

When you upgrade your B Series Appliance from either one physical B Series Appliance to another or between a physical and an RS Virtual Appliance, you must both install the new B Series Appliance and transfer data from the original B Series Appliance.

> For full details about SSL certificates and BeyondTrust, please see [SSL certificate setup](on-prem-ssl-certificates).

1. Choose the default certificate you wish to serve to clients.

   1. On your new B Series Appliance, go to **/appliance > Security > Certificates**.

   2. In the **Security :: Other Certificates** section, locate the entry for your SSL certificate. This usually has an **Issued To** field containing the fully qualified domain name of your B Series Appliance (e.g., support.example.com).

   3. Confirm there are no warnings listed for the new certificate.

      > ℹ️
      >
      > If there is a warning, please see the [Customer portal](https://beyondtrustcorp.service-now.com/csm).

   4. Once all warnings are resolved, in the **Default** column, select the radio button for the certificate you wish to make default.
2. Install the new software package.
   1. On your new B Series Appliance, go to **/appliance > Updates**.
   2. Either click **Check for Updates** or use the **Appliance Download Key** per the on-screen instructions.
   3. Click **Install This Update**. A EULA will need to be signed prior to installation.
3. Import your software configuration settings from the old B Series Appliance.
   1. Log in to your new B Series Appliance's /login interface. The first-time login credentials are **admin** and **password**.
   2. Go to **/login > Management > Software** .
   3. In the **Restore Settings** section, browse to the backup file you downloaded earlier and then click **Upload Backup** to restore the backup to the new B Series Appliance.

At this point, you can update your DNS server to direct traffic to the IP address of the new B Series Appliance, and you can start testing Secure Remote Access on your new B Series Appliance. Once you have confirmed that it is functioning properly, you can return the old B Series Appliance, if physical, or delete it, if virtual. To return a physical B Series Appliance, take these steps:

1. Log in to the **/appliance** web interface of the old B Series Appliance.
2. Browse to the **Status > Basics** page, and click **Reset Appliance to Factory Defaults**.
3. Wait for the reset to complete, and then click **Shut Down This Appliance**.
4. Package the B Series Appliance for shipping.
5. Affix the BeyondTrust return shipping label to the outside of the box and contact your shipper for a pickup. If you do not have a label for shipment, contact [BeyondTrust Technical Support](/#support).
