For any changes to database model we will have to write automated scripts that will upgrade the old data model to the new one. For example, if we add a new required schema like - inventoryContainerType: Joi.string().valid('outlet', 'warehouse').required() to the inventory collection, then we will have to update all existing documents with the mentioned property.
