When and Why should you upgrade to Magento 2.x?

It’s been more than a year now since the Magento 2 series got launched. The GA version of Magento 2 launched in November 2015. Magento will most likely quit supporting the 1.x Enterprise Editions in November 2018. Though many existing users of Magento’s 1.x series has upgraded, a majority of the user community is yet to upgrade. People who have invested in getting a new store built in 2015 will not prefer upgrading because upgradation to Magento 2 means a lot of rework from scratch.
