You can upgrade to the newest release of the product to take advantage of new features. To install a new version of the software, you must perform certain tasks to ensure a successful upgrade. You should also check the known issues that appear in the release notes for any late-breaking information relating to upgrades.
This section is specific to upgrading the software in environments where a compatible version of the product is already installed.
Before you upgrade, review the following information:
Symantec recommends that you do not perform third-party installations simultaneous to the upgrade of Symantec Endpoint Protection. The installation of any third-party programs that make network- or system-level changes may cause undesirable results when you upgrade Symantec Endpoint Protection. If possible, restart the client computers before you upgrade Symantec Endpoint Protection.
Table: Process for upgrading Symantec Endpoint Protection
Step 1: Back up the database
Back up the database that Symantec Endpoint Protection Manager uses to ensure the integrity of your client information.
Step 2: Break the replication relationship (optional)
If the management server you want to update replicates with other management servers, break the replication relationship. If the second management server, or replication partner, launches replication during the upgrade, it may have unpredictable results.
Breaking the relationship between the management servers is not the same as removing the replication partner. You do not want to delete the replication partner entirely.
When Symantec provides updates to client installation packages, you add the updates to 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 Windows and Mac 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.
