Overview of the upgrade process
Upgrading to the current version of Symantec Endpoint Protection includes the following steps in order:
- Create a plan
Before you begin to install the Symantec Endpoint client, manager, and any administration upgrades, you should have a solid understanding of your network topology and a streamlined plan to maximize the protection of the resources on your network during the upgrade. Symantec strongly recommends that you upgrade the entire network to the current version rather than managing multiple versions of Symantec Endpoint Protection.
- Backup up the database
Before you upgrade, you should back up the database.
-
Disable replication
If your site uses replication, you must disable replication before upgrading Symantec Endpoint Protection Manager. You must disable replication at each site that replicates.
- Enable local authentication
If you use Symantec Network Access Control, then enable Local Authentication prior to upgrade.
- Disable "Protect client files and registry keys" Application Control Policy
If you are upgrading from Symantec Endpoint Protection 11.x and use Application and Device Control, you must disable the setting "Protect client files and registry keys" in the Application Control policy prior to the upgrade. After those clients have updated their policy, you may proceed with the upgrade.
WARNING: If this setting is not disabled, you may face issues at a later stage when upgrading your clients.
- Stop the Symantec Endpoint Protection Manager service
Before you upgrade, you must manually stop the Symantec Endpoint Protection Manager service on every management server in your site. After you upgrade, the service is started automatically.
WARNING: You must stop the Symantec Endpoint Protection Manager service before you upgrade, or you will corrupt your existing installation of Symantec Endpoint Protection Manager.
- Upgrade the Symantec Endpoint Protection Manager
You do not need to uninstall management servers before you install the new version. The overinstall process saves your settings, and then upgrades to the latest version.
- Enabling replication after upgrading
After you upgrade all servers that used replication, including the servers that were configured for failover and load balancing, you must re-enable replication. After migration, you add a replication partner to enable replication. You only need to add replication partners on the computer on which you first installed the management server. Replication partners automatically appear on the other management servers.
- Upgrade the Symantec Endpoint Protection Clients
You do not need to uninstall previous clients before you install the new version. The overinstall process saves your settings, and then upgrades to the latest version.
