Again I dont see the most important feature....EASY UPGRADE from Vx...or easy upgrade to...

Is madness of one version per year is something that holds me back to fully abandon our system and go fully odoo...its impossible to have a mature software with all the apps in 24 months specially when everything changes, including data structure.

From all the systems we have odoo IS the most difficult to upgrade and the only one requiring to mess with the data for each version...

I find this strategy perfect for version scatter and thus improper maintenance. I find difficult to believe one reseller can indeed support V5 to v8/9 with the same quality.
