General Upgrade Notes
- As with any application, it is always advisable to perform a backup of your LCE installation and archived logs before upgrading.
- Detailed instructions and notes on upgrading are located in the Log Correlation Engine 4.8 User Guide.
- The supported upgrade path to 4.8.0 is 4.6.1, 4.6.0, and 4.4.x. If you have deployed LCE < 4.4.x, please perform an intermediate upgrade to LCE 4.4.x, then upgrade to LCE 4.8.0.
- LCE version 4.8 is compatible with SecurityCenter version 126.96.36.199 or later. Older versions of SecurityCenter will work with LCE 4.8 without issues, but will not support some new features.
- LCE version 4.8 is compatible with LCE Clients version 4.0.0 or later. Older LCE Clients will not be able to log in and send event data to LCE 4.8.
- Please contact Tenable Support at email@example.com if you have any questions about compatibility issues.

New Features and Improvements:
- LCE Client Management UI: LCE server 4.8 can manage clients that report data to it. The new Client management UI allows users to use the LCE server as a one stop shop for all client management options. Users can assign policies, rename clients, and authorized and delete clients all from the same screen. Multi-LCE organizations may manage clients locally via the LCE UI without using SecurityCenter.
- LCE Client Policy Editor: The new Client policy editor guides users in creating and editing client policies. The policy editor provides a complete listing of LCE clients and allows customers to configure policy and options for all clients. The policy wizard walks users through policy modifications by showing all possible options for the selected client type, and validating them on-the-fly using a simple editor that requires no knowledge of the format of the policy. Advance users may still use the adjacent XML editor to edit the raw policy contents, if desired.
