Once the SEPM has been migrated to 12.1RU5, Upgrade the Symantec Endpoint Protection clients
You do not need to uninstall previous clients before you install the new version. The overinstall process saves the client settings, and then upgrades the client to the latest version.
Note: Clients that are Group Update Providers (GUPs) should be upgraded before other Symantec Endpoint Protection clients. (GUPs are not a feature of Small Business Edition.)
Review the applicable steps to prepare computers to install Symantec Endpoint Protection 12.1.x clients, and choose from one of the available methods to upgrade clients to Symantec Endpoint Protection 12.1.5:
- Auto-Upgrade: Assign client packages to groups in the manager console, either manually or by using the Upgrade Clients with Package wizard.
For Symantec Endpoint Protection Small Business Edition clients, this occurs automatically after you upgrade the Symantec Endpoint Protection Manager. No further action is required on your part to complete the upgrade process. To disable automatic upgrades, in the console, go to the Computers page, right-click your Group, click Properties, and then check Disable Automatic Client Package Updates.
- LiveUpdate – In the manager console, permit product updates through the LiveUpdate Settings policy for a client group (enterprise version only).
- Installation File - Use the installation file you download from Symantec FileConnect to upgrade the client.
- Client Deployment Wizard - Run the Client Deployment Wizard in the manager console. This wizard walks you through the creation of a client package that can be deployed via a web link and email, remote push, or saved for later local installation. In the enterprise version, you also have the option to deploy using third-party tools.
