MIVA runs on DBF files. You'll find them in the htsdata folder in your acount. They are custom DBF files and I have yet to find someone who can convert them to mySQL. There is one application that cost $995 at mvcool.com that does this, but I don't need it THAT bad. Pretty much you need a MIVA coder to customize MIVA, but there are lots of modules out there already. I would highly recommend mvcool.com.
