Everything happens on the old site. New site doesn't matter.
The config file exists. If it didn't, Apache would not run. I don't know where it lives on a production server; all I know is that MAMP has a directory called "conf" and this is probably not much help :)
In some obscure directory that doesn't currently have a named index.xtn file, make an htaccess file containing the single line
If overrides are permitted, you will now get an auto-index of the directory. If instead you get a 403, you really need to find that config file. (If everything is already auto-indexed by default, make it say -Indexes to test.) This is not a 100% reliable test, because auto-indexing is not the same override category as mod_rewrite. But it's a quick-and-easy thing to try.
