Upgrade from prestashop 1.6.1.9 to 1.7

Question

Is it posible to upgrade from prestashop 1.6.1.9 to 1.7? Where is the official documentation?

Answer 1

At this time it's not possible. Check comments here: http://build.prestashop.com/news/prestashop-1-7-0-0-released/

Probably it will be available in the future; at this time you can only export products, categories and customers from 1.6.x to 1.7.x
