Thanks for your question about changing versions of Magento from 1.9 to 2.0. So, Magento never designed an upgrade path from 1.x.x. to 2.x.x. Magento 2.0 was designed to be a separate version of Magento altogether. So, there's a way to do it, but it's not easy and I don't recommend it. Basically, you would have to export all of your data (customers, products, categories, sales transactions) and then import this into a fresh new installation of Magento. It's a lot of work and there's lots of opportunity for mistakes or errors during the process.
Is there a specific reason you wish to switch major versions of the software?
