Why am I required to upgrade the SGOS version on my ProxySG appliance? What happens if I do not upgrade to one of the recommended versions?
URGENT: SGOS/AVOS Upgrade Required by July 4, 2013
Effective February 28, 2013 Blue Coat has removed all non-compliant SGOS/AVOS software versions from the BlueTouch Online (BTO) download site. This action was taken to ensure our customers upgrade to a compliant software version containing the new Licensing Subsystem.
Blue Coat is upgrading its licensing subsystem. Current ProxySG appliances require a license to enable the appropriate software features for the license edition installed. During the upgrade of the licensing subsystem, Blue Coat will provide a transition phase where any valid licensed edition will continue to function with no change in behavior. However, you must upgrade all your devices to the recommended SGOS version before the end of the transition period, which is July 4, 2013. To reiterate: you must upgrade the SGOS version, not the license file. This upgrade delivers support for the new licensing subsystem and will allow your appliance to function seamlessly beyond the end of the transition period, which ends on July 4, 2013.
Note: If you do not have a valid Blue Coat support contract, you are eligible to upgrade to a version within the same release train only. If the release train is no longer supported, you must upgrade to the SGOS version recommended in the Technical Field Alert.
Failure to upgrade to the recommended SGOS version before July 4, 2013, will render the appliance as unlicensed and non-functional when any of the following events occur:
For the Proxy Edition license: The appliance stops processing traffic. All requests will be blocked, and an exception page will display to notify users that the appliance is unlicensed.
For the MACH5 Edition license: In an explicit deployment, the appliance stops processing traffic. All requests will be blocked, and an exception page will display to notify users that the appliance is unlicensed. In a virtually inline or physically inline deployment, the appliance will fail to wire and allow all traffic to pass through the appliance. The policy rules configured for your network will no longer be enforced.
Please refer to the Technical Field Alert for a list of versions that support the new licensing subsystem; the alert contains the list of recommended versions referred to below.
*Please Note: All upgrade actions will require that the proxy be restarted in order for them to take effect.
