Upgrading the LCE Server

The following table lists the upgrade paths for the LCE server with links to release notes, as well as the compatible versions of SecurityCenter and LCE clients. If you have a version of LCE that does not appear in the From... column corresponding to the version you are trying to upgrade to, you must first upgrade to an intermediate version.

Upgrade to... From... Compatible versions of SecurityCenter Compatible LCE clients
4.8.1 4.8, 4.6.x SecurityCenter version 4.6.2.2 or later.

Clients version 4.0.0 or later. Older LCE clients will not be able to log in and send event data to LCE 4.4 to 4.8.

4.8 4.6.x, 4.4.x SecurityCenter version 4.6.2.2 or later.
4.6.1 4.6, 4.4.x SecurityCenter version 5.1 or later.
4.6 4.4.x SecurityCenter version 4.6.2.2 or later.
4.4.1 4.4, 4.2.2 SecurityCenter version 4.6.2.2 or later.
4.4 4.2.2 SecurityCenter version 4.6.2.2 or later.

LCE will work with older versions of SecurityCenter than those listed, but some new features will not be supported.

After the upgrade, changes to the LCE configuration will be done using the LCE interface. To access the LCE interface navigate to the IP address or hostname of the LCE server over port 8836 (https://<ip address or hostname>:8836). The previous configuration files are stored in /opt/lce/tmp and may be deleted once the upgrade is determined to be successful.
