Back up the database
Back up the database that Symantec Endpoint Protection Manager uses to ensure the integrity of your client information.
See Backing up the database and logs.
Turn off replication
Turn off replication on all sites that are configured as replication partners to avoid any attempts to update the database during the installation.
See Turning off replication before migration.
If you have Symantec Network Access Control installed, enable local authentication
Enforcers are not able to authenticate clients during an upgrade. To avoid problems with client authentication, Symantec recommends that you enable local authentication before you upgrade. After the upgrade is finished, you can return to your previous authentication setting.
Stop the Symantec Endpoint Protection Manager service
You must stop the management server service before you install a newer version.
See Stopping and starting the management server service.
Upgrade the Symantec Endpoint Protection Manager software
Install the new version of the Symantec Endpoint Protection Manager on all sites in your network. The existing version is detected automatically, and all settings are saved during the upgrade.
See Installing the management server and the console.
Turn on replication after the upgrade
Turn on replication when the installation is complete to restore your configuration.
See Turning on replication after migration or upgrade.
Upgrade Symantec client software
Upgrade your client software to the latest version.
See About upgrading client software.
When Symantec provides updates to client installation packages, you add the updates to a Symantec Endpoint Protection Manager and make them available for exporting. You do not, however, have to reinstall the client with client-deployment tools. The easiest way to update clients in groups with the latest software is to use AutoUpgrade. You should first update a group with a small number of test computers before you update your entire production network.
See Upgrading clients by using AutoUpgrade.
You can also update clients with LiveUpdate if you permit clients to run LiveUpdate and if the LiveUpdate Settings policy permits
See Managing content updates.
