Comment 27 for bug 1649341

So this hasn't been fixed for the upgrade yet. The issue with the upgrade is that the database needs to have been configured prior to the upgrade occurring and we just landed support for this on the undercloud in Ocata. The api db sync has to happen before the cell setup on new installs and the upgrade needs to have the cell setup before the api db sync. Because of this distinct ordering issue, we may need to raise this as something that needs to be backported to Newton to get the cell setup prior to the upgrade. Alternatively if there's a way to handle specific N->O upgrade actions, that might also be a solution.
