xTuple ERP+CRM 5.0.0 is a big release. A lot of features have been added that should make life better for application users. The price we pay for that added richness is that the internals have changed. Power users and administrators need to do work to upgrade to 5.0.0 successfully. We strongly recommend piloting the 5.0.0 release candidate.
This article describes how to prepare for the upgrade to xTuple ERP+CRM 5.0.0. The goals are to help you prepare for the upgrade over time, improve your production database as you go, give you practice for the production database upgrade, and minimize last-minute work. Keep checking back; we'll improve this article as we get feedback from customers and partners [updated June 14, 2019].
