Resolution

URGENT: SGOS/AVOS Upgrade Required by July 4, 2013

Summary

Effective February 28, 2013 Blue Coat will remove all non-compliant SGOS/AVOS software versions from the BlueTouch Online (BTO) download site.  This action is being taken to ensure our customers upgrade to a compliant software version containing the new Licensing Subsystem.

 

This Blue Coat Technical Alert applies to all versions of SGOS 3.x and greater (including versions of 4.x, 5.x and 6.x) and all versions of AVOS.  Blue Coat has identified a need to update our licensing system within our existing SGOS and AVOS licensing mechanisms.  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.  In order to address this issue and upgrade to a new, more flexible license mechanism, Blue Coat requires all users of SGOS and AVOS to upgrade to a new version of SGOS and AVOS containing a new licensing subsystem by the end of this transition phase on July 4, 2013. 

In order to make this transition as easy and smooth as possible, Blue Coat will offer versions of SGOS with the new licensing subsystem in the major releases of SGOS v4.x, 5.x and 6.x. While Blue Coat does recommend customers with entitled support contracts upgrade to the latest versions (including our recommended releases) of SGOS, specific versions of earlier SGOS with the licensing change will be fully supported and available as indicated in the chart below. 

Customers who are not currently under an entitled support contract, will need to upgrade their ProxySG to a updated version within the same release train.

For ProxyAV, two new versions of AVOS, version 3.4.2 will be available for all ProxyAV customers.

 

What happens if I do not upgrade my SGOS/AVOS version?

For those customers running versions of SGOS or AVOS using the older licensing subsystem, Blue Coat SGOS on ProxySG and AVOS on ProxyAV appliances will continue to operate normally through July 4, 2013.  By July 4, 2013, all customers should have transitioned to a newer SGOS and AVOS with the new licensing subsystem. 

For those customers that have not upgraded their ProxySG appliances to a newer version of SGOS with the new licensing subsystem by July 4. 2013, those ProxySG devices on older SGOS releases will continue to operate normally until the next licensing event.  A licensing event includes a reboot, crash, or other licensing event (such as changing the license to trial mode).  As long as the customer upgrades to a release supporting the new licensing subsystem before a licensing event occurs, the system will continue to operate normally.  If a licensing event happens after July 4, 2013, on a system that has not been upgraded by this date, the system will display a licensing error and may no longer process proxy requests. The customer will then need to upgrade to a supported SGOS release before the system will continue to operate.

What version of SGOS or AVOS should I upgrade to ? 

Ideally, customers should run one of the recommended releases for their platforms.  For customers with entitled support contracts, this would be a version of SGOS 6.2 that is higher than SGOS 6.2.9.1.[1]  If you happen to have 200 or 210-5 platforms the recommended release would be a version of SGOS 5.5 greater than 5.5.9.1 (e.g. the 5.5.10 release available by Sept 21, 2012)

If you need to stay with your current SGOS version or you are a customer without an entitled support contract, Blue Coat will make available multiple versions of SGOS that will contain the license system upgrade as indicated in the chart above.  For example, this will allow users currently running SGOS 4.x, who would like to stay in the SGOS 4.x family the option to upgrade to SGOS v.4.3.5, for a customer running 5.3.x, they could upgrade to SGOS 5.3.4 to stay with the SGOS 5.3 version of the operating system.

Note: customers without entitled support contracts must remain in the same SGOS train (with the exception of SGOS 3.x which must move to SGOS 4.3.5), as their devices cannot upgrade to a newer SGOS train without a change in licensing terms.

All AVOS customers should move to AVOS 3.4.2 when they are released in October 8, 2012.  We do recommend customers to move to 3.4.2 when possible to remain on the most current release.

 

When will the new SGOS and AVOS versions be available?

SGOSv.6.2.10.3 is already released and was available on August 20, 2012.

All other SGOS releases are planned to be available by September 21, 2012 on BTO.  All entitled support customers will have access to these releases with their BTO credentials.

The AVOS release, 3.4.2 with the upgraded licensing subsystem will be available by October 8, 2012.

 

Where can I get more information ?

For additional assistance with upgrading your SGOS or AVOS version, please visit https://bto.bluecoat.com, and there is also a knowledge base article FAQ2197, with more details on this change.



[1] Customers on ProxySG platforms with less than 4GB of memory and a single processor, are near CPU capacity, and running a SGOS release prior to 6.x should consider staying on their current release train.  For example, a customer running SGOS 5.2.x on a ProxySG 210-10 at 70% CPU load should upgrade to a release in the 5.x family.  Platforms with 4GB or more, and multiple processors should have no performance impact and some performance gains when moving to SGOS 6.x.  If you need assistance to determine the effect of SGOS 6.x on your platform, please contact your local SE or channel partner SE.
