When upgrading the following, you want to know which releases are most stable compared to other releases. While a release may have new features and functionality, you may consider it less stable for your network environment.
This article pertains to:
There are several types of releases of SGOS for Edge SWG and ASG, which offer various levels of stability vs features.
This type of release is considered the most stable, with the following goals: stability, reliability, fit-for-use, FIPS/CC certified, and customer satisfaction.
This type of release is often considered for its new features, with goals to increase stability and provide security fixes.
This type of release is the most recent, and generally would not be considered stable. Normally, the focus on this type of release is on feature enhancements. Currently, however, the latest feature release is becoming more stable than generally expected as it is transitioning into its role as Long Term Release (LTR). Therefore, at this time Symantec recommends considering upgrading to the latest feature release for stability as well.
This type of release is available early for customers to use in a lab environment. This allows you to test the changes and see how they will affect your current network traffic behavior
Note: Symantec always recommends staying on the latest maintenance release, on the current branch release you are running, unless a specific fix or feature is required in another release or the current branch release is nearing EOL.
Before upgrading, consult the SGOS upgrade path and guide or the ASGOS upgrade path and guide accordingly
