For SEP 14.3.x agents managed by Integrated Cyber Defense Manager (ICDm), administrators may want to temporarily suspend the auto-upgrade to SEP 16 and maintain version 14.3.x for the time being.
Modify your System Policy using one of the following methods:
Go to [Product Upgrade Settings] - [Enable Auto Upgrade] - [Show Advanced]. Move the [Release channel] slider to "Previous release channel" and save/apply the policy. The "Previous release channel" will continue to deliver SEP 14.3.x for the foreseeable future.
Go to [Product Upgrade Settings] and toggle [Auto Upgrade] to the OFF (left) position to disable the auto-upgrade feature entirely.
