I wish I had learned about this company weeks ago. The service is INCREDIBLY reasonable and quick. I spent weeks trying to use Magento's official tool to migrate from 1.9 to 2.1. I spent more time than I could imagine reading, researching and trying. the fact of the matter is, it isnt simple. These guys have a software that makes it very easy. not only that, their support is FAST and PROFESSIONAL. They sat with me through multiple demo migrations, fixed issues, and even offered to help me with a very unique issue I had with my migration regarding images. Definitely, DEFINITELY recommend!
