There are several database changes that are likely to fail while attempting to upgrade from a pre 1.10 to a 1.10 or later version if an implementation has orders stored in the database. Below are some key conditions that need to be satisfied before attempting an upgrade because they are guaranteed to halt the upgrade if they are not.

Preparing for the upgrade


Upgrading from an earlier platform like 1.6.x

The above guide may demand either upgrading from an earlier version such as 1.6.6 to 1.9.x (which creates the providers table) and then from 1.9.x to 1.10.x or 1.11.x

The MoH Rwanda upgrade lead has written a module that handles all these requirements/steps so that the user only has to install it before upgrading and do nothing else as suggested by this page but go straight to the upgrade steps.

This module supports upgrading from 1.6.x on which it has been tested to 1.11.x


Now you are ready to upgrade to 1.10 or later!
