Existing web server configuration

[Innocentus]

I want to install the zabbix web frontend.
But there is already an existing web server configuration with websites and confixx.

Now I fear that the installation of the zabbix web frontend debian package would overwrite everything I have done.

Where can I get only the PHP-/HTML-/Asset-Files for the zabbix web frontend?
Or can I safely install the zabbix web frontend package without overwriting my old server configuration?

Thank you for your help!
With best regards

I think you take the wrong approach here. Just look at packages.debian.org and figure out the files that are in the package. Only if they indeed overwrite existin stuff (which I doubt), then you can use the frontend without a package..
