Step 1: Back up the database

 Back up the database used by the Symantec Endpoint Protection Manager to ensure the integrity of your client information.

Step 2: Turn off replication

Turn off replication on all sites that are configured as replication partners. This avoids any attempts to update the database during the installation.

The Symantec Endpoint Protection Manager service must be stopped during the installation.

Step 4: 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.

Step 5: Turn on replication after the upgrade.

Turn on replication when the installation is complete to restore your configuration.

Step 6: Upgrade Symantec client software

Upgrade your client software to the latest version.
