In order to reduce the potential impact of unforeseen issues in certain content updates such as definition engines (Eraser engine, AV Engine, and so on), Symantec is implementing a system of staged rollouts for these updates. This document describes the concept of staged rollouts, and how clients and managers receive definitions during a staged rollout.
Staged rollouts are Symantec's way of slowing down the release of certain updates, so that in the unlikely event of problems with the updates, fewer computers are affected. This is implemented by updating Symantec Endpoint Protection Managers (SEPMs) of certain versions before other versions.
A staged rollout works as follows:
Since most environments use a single version of SEPM (multiple SEPM versions in a single environment are not supported), staged rollouts should cause no visible effects in most cases.
