Kiwi Syslog Server NG SQL

Installed a new version of Kiwi Syslog Server NG. We have the lagacy version of Kiwi Syslog running in production and it is using SQL server. How do I configure SQL for Kiwi Syslog Server NG? Is this database supported with the newer version? I am not finding any documentation on SQL and Kiwi Syslog Server NG. I am not getting anywhere with technical support. I want to use Kiwi Syslog Server NG with SQL so we can log everything. 

Thanks.
