About software updates

Symantec periodically releases new versions of the Symantec Messaging Gateway software. New versions contain new features and fixes for software defects. Symantec recommends that you keep your appliance up to date with the latest version of the software. However, some software updates may contain changes to the underlying architecture of Symantec Messaging Gateway. Always read the software update notes and release notes for specific instructions before you run the update.
You must run software update on the Control Center and all Scanners. The order in which you apply the software updates to your appliances does not matter. For example, you can update the Control Center before you update Scanners or update a Scanner before the Control Center. Update one appliance at a time.
