    There is no magic here, the Mage will need to remove his shirt and start engaging in actual physical labor. magento.stackexchange.com/questions/87007/… Nov 19, 2015 at 7:43

It is not possible to use Magento 1.x extensions and design themes with Magento 2 without code refactoring.
There is the official code migration tool which can help the developers to migrate theirs extensions and design themes: https://github.com/magento/code-migration
But the tools is for experienced developers only.


The architecture of Magento 1.9x is entirely different than Magento 2.x so technically it's not possible to migrate a Magento 1.9.x to 2.x without actually changing the entire theme architecture. Magento 2.x is not backward compatible with Magento 1.9.x so it's NOT possible.
