Upgrading from complete syslog-ng PE to client setup version of syslog-ng PE
The installer displays the following message if you try to upgrade from complete syslog-ng PE to client setup syslog-ng PE with .run package.

Uninstalling syslog-ng PE
If you need to uninstall syslog-ng PE for some reason, you have the following options:

Steps:
-

Create a new database user and associate it with the new database.
-
Figure 22: Creating a new MSSQL user 1.
