Since OTRS 2.0 it is possible to change nearly all configuration parameter of the ticket system through the web interface. The new graphical configuration frontend makes it possible.
The "SysConfig" link in the admin area of OTRS loads the graphical configuration frontend. You can upload own config files for the system and backup all your current settings into a file. Almost all config parameters of the OTRS framework and the installed applications can be viewd and changed through the web interface. Because all config parameters are sorted into groups and sub groups it is possible to navigate quickly through the multitude of the parameters. Also it is possible to mae a full-text search through all the config parameters.
In the chapter "Configuring the system through the web interface" the graphical configuration frontend is described more detailed.
