I’ve definitely made bigger mistakes, but we also had an Oracle DB that could INSERT INTO…SELECT FROM -point in time- that pretty much put us back to the point before we started our migration. And of course we had backups rolling all the time, as well as our pre-migration backup. We had a good, competent team, and we overlooked a small but catastrophic detail - it can happen to anyone, the goal should be to have backups and failovers in place because things _will_ fail, at some point, and a contingency plan is just good practice.
