After you download and store the new upgrade file on your local network, upload it to the Grid Master, as follows:

1. From the **Grid** tab, select the **Upgrade** tab, and then click **Upload** in the panel or from the Toolbar.
2. Navigate to the directory where you have stored the NIOS upgrade software, and then click **Open** or **Upload**.

The appliance uploads the file and displays the status of the upload in the status bar. You can click the Stop icon in the status bar to stop the upload. **Ensure that you do not navigate away from the Upgrade tab until after the upload is complete (which is when the Distribute button becomes enabled). Otherwise, the upload process stops.**

Infoblox recommends that you change the default session timeout setting from 600 seconds to 1800 seconds. You can update the setting in the **Security** tab > **Session Timeout(s)** field.
