Apache update cpanel

If I update my apache via cpanel will it overwrite the httpd.conf if I have edited it?

It shouldn’t, no. Not a big deal to copy the file first – you can always copy it back.

Yes, if you update the apache then it will overwrite the httpd.conf file.

I update apache all the time and the conf file is not overwritten. Doesn’t cpanel generate and manage the file anyway?

It depends what type of modifications were performed, but usually your settings should not be changed.
