OsCommece >> OpenCart
" For years our store was running on some fork of osCommerce until we finally decided to upgrade to a more stable and secure platform. We had a huge amounts of data: products, customers, orders, reviews, etc., accumulated over the years and we were in no mood to lose any of it to the new technology. Stefan promised to copy everything and not to lose any uptime in the process. I was amazed at how quick and seamless was the whole process. All customer's accounts complete with passwords worked perfectly, order history, comments, tracking numbers, everything was in place.
Not planning another platform change anytime soon, but if we did, we will come back to you.
