Especially egregious given that, since it was voluntary on the bank's part, they could simply (haha) have transitioned different people at different times. Start with transitioning a single customer, make sure it goes well, then a few dozen, etc. Spend a little money on incentives for people to volunteer to go early, it wouldn't take that much money to get a few dozen volunteers. It's one thing if it goes poorly in a disaster-response kind of situation, where you could not practice beforehand. But this is a self-imposed transition, with at least some control over the timeline, so they should have been able to find these kinds of issues in beta testing.
