Really good article. Me too I diddn't know about it for a long time.
You might add the precision that it's a data migration (It's even called like that in the docs). The fact is, for beginners who never faced the needs to do a data migration, most of the times when we (as I was in the case) hear about migration we just think about changing database schema, creating table, adding or removing new fields, not changing the data that exists in the database.
