Upgrade to the latest version

New ESET Server Security versions are issued to provide improvements or fix issues that program module automatic updates cannot resolve.

Upgrade methods include:


This method removes the current ESET Server Security version before installing the new one. Download the latest version of ESET Server Security. Export settings from your existing ESET Server Security if you want to preserve your configuration. Uninstall ESET Server Security and restart the server. Perform a fresh installation with the installer you downloaded. Import settings to load your configuration. We recommend this procedure if you have a single server running ESET Server Security.


This is an upgraded method where you install the new ESET Server Security version over the existing version.


You must not have pending Windows Updates on your server and or pending restarts. If you try performing an in-place upgrade with pending Windows Updates or restarts, the existing ESET Server Security version may not uninstall correctly. You will also experience problems if you manually remove the old ESET Server Security version afterward.


A server restart is required during the ESET Server Security upgrade.


This method is used in large network environments managed by ESET PROTECT, and is a clean upgrade method carried out remotely. It is useful if you have multiple servers running ESET Server Security.

ESET Cluster wizard

You can also use the ESET Cluster wizard to upgrade in-place. We recommend this method for two or more servers with ESET Server Security. When the upgrade is complete, you can continue using ESET Cluster and its features.


When you upgrade your ESET Server Security, we recommend you go through all the settings to ensure it is configured correctly according to your needs.
