It was the alterations to the old database that caused every upgrade script to fail, and why this upgrade, just the actual live database dump and import itself, took 48 straight hours as well as weeks of preparation prior to that.

I've alerted the editors to the question, that's the best I can do. I'm sure they'll be along to answer shortly.
