I just spend a lot of time building a Wordpress online store to replace an old Joomla one. Cart2Cart has what they call a Demo Migration. I thought it would demonstrate what Cart2Cart was like to use and what the results would look like. Turns out it wiped out most of the work I had done and to have it fixed they have to get into my old and new sites, which I don't trust at all. Now I'm looking at redoing hours and hours of work. Cart2Cart is expensive and not worth beans. Zero stars.
