Also using a key value store or some other no-sql non-graph storage can sometimes be put between two structured migration endpoints. The advantage is that you have a clear way to first pull things apart before you put them together again and an intermediate step that is durable and easy to analyze. But I think the article doesn't talk about full data migrations or integrations of two very distinct models, but rather about incremental, on the fly migrations on production databases, so the above doesn't apply well I think.
