I am following openererp since version 5. Why there is no easy way to upgrade? Is it beacause of commercial gain? I love odoo and appreciate its being free but for each new version we setup new database and go on. 

I heard about Openupgrade will wait until they finish upgrade script for 11 https://github.com/OCA/OpenUpgrade

But why odoo do not help community in this issue?

Before odoo 10 I was not concern about upgrade as a big issue because they were changing structure. But now odoo 11 is similar to 10, so why there is no easy upgrade?

Best regards... and thank you for odoo...
