Yes. If you have an existing Apache configuration, you can still keep that and use the CollabNet Subversion Edge console.
In most scenarios, you should be able to set up the server using the web interface. For any additional configuration, you can edit httpd.conf located in /data/conf in the directory where you installed Subversion Edge. If you have the ROLE_ADMIN or ROLE_ADMIN_SYSTEM role, you will be able to start and stop the server from the console.
