If you have multiple servers in your site, you can choose to upgrade all servers through the Client software rather<br />
than update each server manually at their physical location. This feature is especially helpful when you have an<br />
enterprise system with up to 100 servers in a site.<br />
Tip: To avoid losing video connection, set up failover connections before you perform an upgrade. This allows<br />
cameras to connect to a secondary or tertiary server when the primary server is required to restart as part of the<br />
upgrade process. For more information, see Failover Connections on page 26.<br />
Tip: After you perform each step in the Site Upgrade dialog box, you can close the dialog box and continue<br />
regular operations. Be aware that cameras will briefly disconnect from the system when the server restarts as<br />
part of the upgrade process.<br />
1. Download the latest version of the Avigilon Control Center Server software or Edge Solution (ES) device<br />
firmware from the Avigilon website: http://www.avigilon.com.<br />
2. In the Client software, log in to the site.<br />
3. In the site Setup tab, click .<br />
The Site Upgrade dialog box is displayed. The dialog box lists all the servers that are in the site.<br />
If the site contains an ES camera or recorder, the Platform column is displayed. The column displays the<br />
device model number to help you identify which upgrade package you should use.<br />
4. In the top-right corner of the dialog box, click Upload.<br />
5. In the Open dialog box, locate the installer that you downloaded from the Avigilon website.<br />
6. In the Confirm Selected Installer dialog box, confirm that you've selected the correct installer then click OK.<br />
The dialog box displays the installer details in the Installer Info area and lists the servers that can be<br />
upgraded by the selected installer.<br />
The new installer is uploaded to one server then distributed to the other affected servers in the site. It<br />
may take several moments before the installer is fully uploaded.<br />
When the installer has been distributed to each server in the system, the Upgrade button is displayed<br />
beside the servers that can be upgraded by the new installer. The button is disabled until the installer has<br />
been distributed to all servers.<br />
7. Click Upgrade beside a server.<br />
a. When the confirmation dialog box is displayed, click OK to allow the server to reboot as part of the<br />
upgrade process.<br />
When the server restarts, it will disappear from the list then reappear after it reconnects with the<br />
system.<br />
To facilitate the failover connections, it is recommended that you wait for each server to complete<br />
the upgrade process before upgrading the next server.<br />
b. Repeat this step for each server in the site.<br />
