The requirements and resources for upgrading or downgrading SGOS for Edge Secure Web Gateway (formerly ProxySG).

*Important note: For Advanced Secure Gateway (ASG), you will need to follow the upgrade/downgrade path and recommendations from the ASGOS specific release notes and documentation.

We recommend adhering to supported SGOS upgrade paths and ensuring that configuration and policy migrations are done correctly.

Unsupported upgrade or downgrade paths can cause long term unexpected behavior. Ultimately, these could cause a lack stability of the appliance, which could require a factory reset and manual reconfiguration to fix.

For upgrades and release notes, see the following:

• Release Notes - Available under "Product Downloads" on the Broadcom Support Portal.
• SGOS Upgrade/Downgrade - Displays the correct paths to be performed for successful upgrades and downgrades.
• The ASG has a built in CAS and requires the CAS upgrade path is simultaneously followed. See the Advanced Secure Gateway Upgrade/Downgrade Quick Reference.
