Before you begin

Ensure the following:

• You are logged on to the server that has an existing installation of NAS proxy as an administrator. 
• Your server matches the requirements listed in the System requirements section. 
• You have downloaded the latest NAS proxy installer on your server. The installer is available on the Add NAS Proxy page while adding a NAS proxy. You can also download the installer from the Druva downloads page.
• To upgrade a NAS proxy manually, it is recommended to install a new version of the NAS proxy without uninstalling the existing old proxy. This avoids the need of re-registration of the proxy with Druva because the uninstallation process removes all the logs and the configuration-related information from the server.

To upgrade NAS proxy

1. Go to the location where you have downloaded the NAS proxy installer.
2. Double-click the NAS proxy installer.
3. Click Next. 
4. In the Install location box, type or select the full path to the installation home directory. 
5. Click Install.
6. After the installation completes, click Finish.

Note: A system reboot is not required after manual or auto upgrade. After an upgrade, NAS proxy is activated automatically. You do not require a separate NAS proxy activation.
