Of course it is extractable. The question is, how easily doable it is, and how easily insertable it is back to the live version.
As I said, I’ve seen database transfers where the provider told us they could make this extractor tool quite easily, and then magically transfer the database to another. Several months later they admitted they couldn’t do it, but they had messed up another client’s database in the process. And this was a company whose main product is databases.
So if you’re the kind of database wiz you claim to be, and you’re looking for a challenge, I could probably recommend you for a job.
