 To push models to Global Registry, you will need a `global_registry_id` column. You additionally need a
 `global_registry_mdm_id` to pull a Global Registry MDM (master data model) id. These columns should be of type 
 `:string` or `:uuid` and allow null values. Column names are customizable through options.
 ```ruby
 class CreatePeople < ActiveRecord::Migration
-  def self.up
-    create_table :people do |t|
-      t.string :name
-      t.string :global_registry_id, :null => true, :index => true
-      t.string :global_registry_mdm_id, :null => true, :index => true
-    end
-  end

+    add_column :people, :global_registry_mdm_id, :string, null: true, default: nil
