Before you run a software update, Symantec recommends that you prepare your system.
The table below describes the steps to prepare and run a software update.
|System restarts||Symantec Web Gateway automatically reboots after the upgrade finishes.|
|Perform upgrades during off-peak hours||Perform upgrades during off-peak hours since the Symantec Web Gateway service temporarily shuts down during the upgrade.|
|Do not restart||The software update process may take several minutes to complete. If you restart before the process is complete, data corruption is likely. If data corruption occurs, you must reinstall the appliance with a factory image.|
|Close and restart existing browser sessions||After you perform a software upgrade but before you make any configurations, close down all browser sessions. Otherwise, new features may not appear in the Web GUI in an existing browser session after the upgrade completes.|
|Purge events from the Symantec Web Gateway database||
Symantec Web Gateway reports events for all of the traffic that it monitors and stores these events in a SQL database. Over time, millions of events can accumulate. You can see the number of events in the Web GUI on the Reports > Custom Reports page. Change the default date filter to All dates.
